Had a smart key that unexpectedly failed on my Mom as she was having lunch. Luckily, she wasn't far away and was able to bring her the spare key. Called our local MB dealer only to be told that I would have to drop off the car for them to diagnose even though I explained in detail what happened. They wanted $325 just to diagnose the issue. Called another independent MB shop who was able to diagnose the issue (bad key) but referred me to a locksmith who would make a new key but that it would be an aftermarket one. That is when I remembered seeing videos on IG of Star Motor Werks and reached out. Geoff responded within 15 minutes and penciled me in the following week. Decided to make the drive down to Star Motor Werks simply due to the fact that they'd make a new key using OEM parts at an affordable price (compared to a MB dealer). They even loaned me their shop car so that I wouldn't have to wait around as I needed to run a few errands. Couldn't be happier with the service and professionalism provided by Geoff and RJ. Would happily drive an hour and half in the future should I need any major maintenance done on our MB. Glad their vids popped up on my IG feed as they are truly knowledgeable and trustworthy. read more

I first came across Star Motor Werks on Instagram while scrolling through car content. At the time, I had been saving up for a brake upgrade and decided to reach out via Instagram (as suggested on their page) back in 2024. I received an automated response, but unfortunately never heard back. Life got busy, and I eventually forgot about it. Fast forward to a several of weeks ago -- another Instagram ad for Star Motor Werks popped up while I was, once again, deep in car content. This time, I decided to look up their Yelp page. Since I was already there, I used the "Request a Quote" feature and included detailed information about my goals for the project. The very next day, I was contacted by Denise, who was incredibly helpful and responsive. She asked a few follow-up questions and let me know she'd gather details and pricing for me. When she mentioned, "Oh yeah, we've done brake upgrades before!" I was genuinely excited. Her professionalism and friendly attitude immediately gave me confidence that I was in good hands. Shortly after, Geoff made multiple attempts to connect with me and even carved time out of his busy schedule to walk through the specifics of the project. He patiently explained every detail and offered thoughtful, professional recommendations on equipment and pricing. It's clear he truly knows Mercedes-Benz inside and out -- his knowledge and passion really show. I brought my car in for a quick inspection, and we reviewed everything in person. With Geoff's guidance, I ultimately decided to move forward with OEM AMG brakes and parts. Every detail was thoroughly discussed, and we penciled in a date for the project. So far, the experience has been professional, informative, and genuinely pleasant. I truly appreciate the time, transparency, and care the Star Motor Werks team have shown throughout this process. I'll be sure to provide an update once the project is completed, but I'm feeling confident and excited about what's to come. read more

We were referred to Star Werks Motors by Allen Tire next door after replacing all of our tires, and I'm so glad we were. Geoff and his team are exceptional. What really stood out was the level of transparency and care. He took the time to walk us through everything with video and photos of the car, clearly explaining what was done and what to keep an eye on down the road. No pressure, no upsell, just honest, thoughtful service. Our Mercedes is at about 80,000 miles now and it's running beautifully. You can tell they truly know these cars inside and out. We're based in Palm Springs and will absolutely continue to bring our car to Geoff for the bigger service needs and anything more complex. Worth the drive, and honestly the kind of shop you want in your corner long term. read more

The crew at Star Motor Werks are phenomenal, their level of expertise and professionalism are top notch. I also appreciate Geoff for taking the time to send video updates throughout the process of repairs being made. Looking forward to bringing my cars back in the future for all their servicing needs. read more

If you want peace of mind and confidence in the people that are working on your car then this is the place for you. There is not another shop I trust with my car as much this one, and trust me I learned the hard way. Unlike other shops they're not going to try and sell you unnecessary work or do "guesswork" on the car. I took my car in for suspension issues after another shop absolutely mangled the job and still charged me an arm and a leg. Luckily I knew exactly who could save the day & my baby! It was Geoff and his awesome team! It's always a pleasure to work with them as they are super nice and welcoming and like I said with Star Motor Werks the only thing you'll be worried about is where you'll cruise to next in your sweet ride read more

I was referred to Star Motor Werks by buddy of mine where I live in Fresno, CA. He told me that he drives 5-6 hours just to service his C63s and he won't take his car anywhere else. I followed his advice and drove my car down to Costa Mesa and I rented a car from John Wayne airport back to Fresno since my car needs time to get all the services done! I did set up appointment with Denise and I told her that I have to see Geoff.. I saw Geoff and he greeted me and he was very polite and patient while I explained everything what my C63s edition 1 needs. What I like about Geoff that he listen to the customer before he recommends anything. All the minor issues that require attention to detail he was able to fix them that my local Mercedes Dealership couldn't. He did many things, from basic engine oil, transmission & brake fluid as well replacing the spark plugs & gapping them since I got Renntech stage 1 tune.. drive belts, AC recharge, fixing the driver window and rear trunk, replaced car battery and update the infotainment system and few other minor things. I already have Renntech exhaust and exhaust valve monitor and I wanted my car to sound little bit louder. He recommended RedStar catted 200 cel Downpipes with heat shield.. let me tell what! Best mod that I ever done! Sounds absolutely amazing! This is a must for every C63 W205. I highly recommend Geoff and all his staff members as they know what they are doing and Geoff keeps you updated with video clips and explanations. I am ready to drive 5 hours for my next service just to do basic oil change! Thank you Geoff! Very happy customer! read more

This is THE place if you have an AMG. They are very thorough and experienced. The quality of their work is better than a dealer any day. They are also a pleasure to deal with. There's never any feeling of getting anything but a straight forward answer and solution. Highly recommend! read more

I've never met a team so detailed, caring and so great at what they do. They advised me of unnecessary items the dealers recommended and saved me over $1500 worth of work at the very least. I don't often write reviews, but this was certainly warranted. Thank you again SMW! You have a loyal customer for life. read more

Geoff and Star Motor Werks is always amazing. Takes great care of my SL63. Never tries to upsell me on anything unnecessary and is always honest about which repairs are urgent and which are optional. Car is still running great after all these years and comes back looking better than ever after each visit! Thank you! read more

A FREE consultation by Geoff saved me potential headaches and serious money down the line. Just got a G Wagen and brought it to Geoff. He caught a few issues that I would never have known about if it wasn't checked. Was able to get those fixes done by the dealer because Geoff caught it so early. Working with him now to add some deployable running boards - not common for this vehicle - but I am confident with their process and attention to detail that we'll find just the right fitment and quality. read more

Discovered a rattle in the left quadrant of engine compartment. Geoff diagnosed it as a faulty shock and strut assembly. It was leaking badly. After replacing all four shock and strut assemblies and the accumulator, my SL550 AMG runs safely and very smoothly. Thanks Star Motor Werks. Your true skill, knowledge and professionalism has prolonged the life a great automobile. I would recommend Geoff and his crew to any Mercedes owner without any reservation. Keep up the good work. read more

I had a bad experience getting my MB serviced by the dealer. Star Motor Werkz was recommended to me by a friend. I had my car serviced there several times now. It is my go to place for service. I highly recommend Geoff and his team. They are very professional. I totally trust them to do only what is necessary and i know that the work will be top notch. Geoff instills confidence especially from having experience working for one of the top MB dealers. Once you meet Geoff, I believe you will feel confident in trusting him and his team to service you MB. read more

A true Mercedes specialist shop that provides quality Mercedes service at a fair price with the skillset to back it up. Geoff, Denise and RJ provided phenomenal service for my C63 and my car and I left feeling like a million bucks. read more

Geoff and his team are awesome!! Very intelligent and are extremely thorough with the work they do. I took my C63S in for Service B, Lowering Springs, Spacers, Struts, and lastly I had the seatbelts replaced for yellow ones... Now onto the tedious install that Geoff and his team had to endure for 3 weeks since the seatbelts were not right multiple times. First the color was off, then the belts came without being in the correct holes from the store I bought them at.. all in all it was a struggle to say the least but Geoff and his team made sure that I was happy with the end result and worked with me on getting it sorted without ever wanting to throw in the towel. Seriously I think Geoff was pretty close though and I don't blame him haha. Also I just want to mention the attention to detail Geoff provides.. not only would he text me pic updates and or FaceTime me, but since I just had my calipers painted I asked him if he could be careful around them. He then texted me back a picture of them fully taped up so nothing could damage them and told me that's standard when preforming work around that area. Never have I received service like that. Needless to say very happy I found Geoff and his team at Star Motorwerks! read more

Long overdue review! Geoff and the team at Star Motor Werks has been taking care of my W204 C63 for a couple years now and I wouldn't go anywhere else! They offer fair pricing and deliver excellent work. If you need anything done with your Mercedes, come here and know that your car will be in great hands read more

Brought in my G63 AMG in for service and let me tell you, what a wonderful experience I had! Glad I have found a shop/ team that is super honest, respectful, and detail oriented. First time I called and spoke with Denise, super kind and always very helpful. Geoff called later that day to introduce himself also to explained the steps and processes with the repairs. Got a video from RJ with the progress of the repairs. To top it off, got the car back and it was washed Thank you Geoff, Denise, and RJ for all your help and look forward to seeing you all on my next service. read more

It's always nice coming here, Geoff always makes me feel valued, not only as an AMG owner but as a car enthusiast too. I live 100 miles away, and they are always willing to work with my schedule to make sure my car is good. Thank you again for accommodating my schedule!!! read more

Star Motor Werks - 2011 W204 C63 - Auto Repair Near Me - Costa Mesa, California

I highly recommend Star Motor Werks for your car repair! In the past, I have felt completely taken advantage of at car shops, and I have left with a high bill and the problem NOT fixed. At Star Motor Werks, the team was immediately so warm and welcoming and I felt like they actually cared about my safety and well being in my car! They go above and beyond (offered me lunch, a car wash, etc)! Jeff even replaced my car tags for me because he saw that I was pregnant and I did not have the tools to remove the "old tags". It was a VERY refreshing experience to be treated so kindly :) read more

I've been meaning to write this review for a while now, and it's long overdue. I cannot emphasize enough how fantastic Geoff is. I've known him back since around 2010 when he was at The Auto Clinic in Tustin/Irvine and I've finally found him at his latest venture. If you own a Mercedes or probably any European car, this is the go-to place for top-level service and maintenance. Geoff, the owner, is an expert mechanic having spent years at Mercedes. He takes the time to explain exactly what's happening with your car, detailing what needs immediate attention, what might need fixing in the future, and what you can expect down the line. I was pleasantly surprised to get updates with pictures/videos as the service went on. It's that personal touch that makes all the difference. It's rare to find such transparency and honesty in this industry. When you bring a car to Geoff's shop he treats you like family and you can rest assured that your car will be well taken care of. Highly recommend this shop! read more

I recently reached out to Star Motor Werks for an estimate for a front differential service and reseal on my E63S wagon. I had heard about the shop through a friend and the stellar reviews gave me confidence that they would provide top notch care for my vehicle. Geoff and Denise responded quickly to my inquiry and provided a reasonable estimate for the work. I was pleasantly surprised that they were able to schedule me sooner than I expected to have the work done. After dropping off my wagon, they conducted a thorough inspection wagon and identified a few other areas that needed attention. I was most impressed because they identified issues that caused some of symptoms (e.g. uneven tire wear) that were previously identified by the dealer. They provided an estimate for the additional repairs that also allowed for cost savings on the labor charges. I thought the prices were fair for the amount of work that would be done. Geoff provided me with an accurate assessment of the time needed to complete the work and sent video updates to keep me apprised of the progress throughout the week. On the day of the pickup, they also had the car thoroughly cleaned (including the engine compartment) and took time to review all the work that was done and show me the worn parts that were upgraded (even though it was late in the day). Overall, I am extremely impressed by the attention to detail and expertise shown by Geoff and his team at Star Motor Werks. My wife joked that I finally found a shop that was as OCD as I am about our cars. So happy to have found the future shop where I will be having my AMG serviced! read more

Exceptional customer service, wonderful people, great communication, immediate response!

Star Motor Werks is my #1 South County shop to handle any and all maintenance repairs. It's the first time having my new AMG at this shop, which has since had a change of ownership from Chris to Geoff. However, the same top quality of service is present as are many of the original technicians, not to mention the overall exacting standards that Chris established prior to moving out of State. Now here's where things get interesting. I came in for a simple oil change with a Liqui Moly flush + additive. Having said that, I'm all about preventative maintenance. Upon completing the standard vehicle inspection Geoff discovered my rear CCB (carbon ceramic brakes) pads were dangerously low and I was at high risk of damaging the rotors, which are somewhere in the neighborhood of $5K to replace. Geoff was able to quickly source the required parts on the same day and had me back on the road in no time. There are many shops that would have simply completed the requested service, but Geoff at Star Motor Werks went above and beyond, looking out for me and my ride. My wallet is grateful. I'm stoked to see there has been zero decline in the level of service that this shop has always had an amazing reputation for. read more

I found Star Motor Werks through Instagram and I am lucky that I found this shop! I started following Geoff's page and I saw how knowledgeable he is with Mercedes and especially AMG cars. I was having issues with my CLS 63 AMG and the local shop near me could not fix the issue. I'm in the Southbay area but I decided to tow my car to Costa Mesa to have Geoff work on it. Best decision I made. Geoff and his team were very detailed and had great communication regarding the various issues he saw with the car. They took pictures and sent them along with their inspection results. After the work was completed, Geoff stayed after closing hours so I pick up my car. Even though it took me over an hour on the 405 freeway in traffic to get to the shop, I will continue to bring my car to him for service. Great customer service and attention to detail. read more

Exceptional service and very polite. Checked all my lights and let me know one of my head lights was not working. They replaced the build for a reasonable price. read more

Not only is Geoff a true professional he's also a class act, I had a very specific and obscure request that required extensive research. I feel most other shops would've given up or outright refused the job but SMW stuck to it and produced a beautiful result that was as good as I could've hoped for, and this is done while being very patient with answering my constant calls and questions. I would not hesitate to take my car here in the future, especially for jobs that require a special touch and high levels of technical knowledge and skill. read more

Amazing work glad I found this shop had my c63 running in no time definitely my new mechanic

Great overall experience. Took my 2023 CLA 250 in to get its Service B done & the team at Star Motor Werks did a great job in a more than reasonable amount of time. Denise was very helpful and communicative throughout the whole process, keeping me updated on estimated time of completion and was very informative when breaking down the services needed to be performed on my car after it went through the initial inspection. Couldn't recommend Star Motor Werks more to anyone looking to get their car serviced. Competitive pricing as well. read more

Star Motor Werks - 2016 GLE400 V6 Motor - Auto Repair Near Me - Costa Mesa, California

Honestly one of the best car shops we ever been to. Everything was well explained with photos and prices. Best pricing out of all the shops we been to. Employees here are very nice and well mannered and there was no pressure on overfixing our car parts. They showed us some concern places that weren't necessary to fix but to keep an eye on which we really appreciate. They changed our alternator drive belts, transmission fluids and wipers. We were really impressed with Geoff and the rest of the staff. read more

I went to Chris due to an issue the dealer could not identify on my C63S. Several people had nothing but great things to say about Chris, and I can tell you they were all correct. Chris and his team were able to figure out the issue was related to the wheel bearings; he immediately ordered the parts, and made the necessary repairs within 2-3 hours. The work performed was great and I haven't had any issues with my car since then. If you are looking for a great shop, and great customer service, this is definitely the place. read more

I have never been so in awe and appreciative of a mechanic in my life! When I purchased my 2023 GLB 250 a month ago, I found Star Motor Werks on Yelp and reached out to see if they were available to do a full vehicle inspection to make sure I purchased a quality used car without hidden problems. Having inquired first via Yelp, Geoff and his team were quick to respond and offered a competitive price for the used car vehicle inspection. The day after I purchased my car, Geoff was able to get my car in so he and his well-trained team could thoroughly inspect it. Although the shop is small, they were able to finish the inspection by the end of the day and spent time with my husband and me explaining in detail everything Geoff observed. He emailed and went over a detailed report. After that, he was able to educate us on how to take care of my first Mercedes so it will last a long time. The care and concern, honesty and integrity Geoff displayed was heartwarming. All of the people who work at Star Motor Werks are truly wonderful. Leaving the shop, I felt happy that I purchased this car, confident in the Mercedes brand, and relieved that we discovered our new mechanic for the life of the car. I should have written a Yelp review immediately after this fantastic experience, but a few weeks passed and time got away from me. Unfortunately, less than a month after buying my new Mercedes, I was rear ended at a stoplight on my way to work. I was devastated upon impact, but my car didn't look too bad. The way it felt and sounded during the crash did not match how good my car looked. My husband was concerned about possible damage not seen with the naked eye, so he called Geoff at Star Motor Werks to see if he could check it out for us. Geoff said they were super busy that day, but he said my husband could drop it off. My husband dropped off my car and Geoff was able to inspect it for us by end of day. Thank goodness my husband called Geoff because there was in fact damage to my car that he found under the bumper. Geoff took a video of the damage and gave us a detailed report. He even had a solid suggestion for a body shop that we can trust to do the work on my car. I appreciate how thorough, honest, helpful, and kind Geoff is. It is very rare when you leave a mechanic's shop feeling better than when you went in, and in both trips to Star Motor Werks, we left feeling grateful. In the future, I will always bring my car to Geoff and his team at Star Motor Werks, from oil changes to any car challenges. I wish every business owner was this conscientious, trustworthy, and pleasant. read more

I could not say better things about this place!! From the very first experience, Geoff and the entire office made it seamless and transparent, with constant communication the entire way. Not to mention the quality & timeliness of the work done. From bigger issues to maintenance, they are my go-to guys and I now consider them (and the shop cat Rexi) my good friends. They are beyond trustworthy, love what they do, and care so much about their customers! I'll never go anywhere else! Absolute 10/10. read more

Hmmm where do I start. First of all I was foolish enough to purchase a high mileage E55 with no PPI, and it had a laundry list of repairs needed. Lucky for me I was searching YELP for Southern California Mercedes service with 4 stars and was fortunate enough to find Star Motor werks. I communicated with Chris online and he was able to make room for me last minute even though his business was packed. He then repaired almost my entire list of repairs and maintenance items and I am extremely grateful. Not only are his prices fair. Chris is a stand up guy he keeps it straight with you no BS. Oh and did I say his work is phenomenal !!! read more

With virtually 5 out of 5 stars out of almost 200 reviews, what can I say about Star Motor Werks that hasn't been said already... Upon arrival you can tell how much passion this shop has for Mercedes Benz. As an AMG owner, we care about who works on our cars. We want people who understand and appreciate the intricacies of Mercedes Benz, especially when it comes to any work done on a high performance variant such as any AMG. Jeff, Denise, Sandra and Rexxie are all top quality individuals. So far I've experienced nothing but professional, quality work. Thanks to Star Motor Werks my C63 is 12 years old and running like an absolute charm as a daily driver. Highly recommend taking your AMG, or really any Mercedes Benz to Star Motor Werks. You won't be disappointed. read more

Talked to Geoff about my tune for my Mercedes E400. He was really nice about it and we talked about the options available for it. Also was surprised I was able to get an appointment set up for it right away even was possible to fit me into the schedule the next day. He is happy to answer any questions or concerns and do his best too. I would recommend coming to him for sure! :) read more
