    If you own a BMW and want a shop that treats your car like their own, Best Motorwerks in Rancho Cucamonga is the place to go! I recently took my F90-gen M5 in for basic maintenance and spark plug replacement and the service was nothing short of exceptional. From start to finish, the team was professional, knowledgeable, and truly passionate about European cars. They handled everything with precision, ensuring my M5 got exactly what it needed. What really set my visit apart was the owner's personal touch toward the end, they even helped me out with a detail going the extra mile to make sure my car looked and felt its best when I drove away. It's rare to find a shop that combines expert-level service with genuine care for their customers but Best Motor Werks does just that. My car is running smoothly and performing flawlessly and I couldn't be happier with the experience. If you want top-tier BMW care with a personal touch this is the place to go!

    Best Motor Werks lives up to its name in every way. The service here is absolutely top notch--professional, quick, and most importantly, reliable. Every member of the team is friendly and personable, and you can tell they genuinely care about your car and your experience. What really sets them apart is their deep knowledge and skill across so many brands--Audi, Porsche, Lamborghini, Mercedes, BMW--you name it, they do it, and they do it exceptionally well. Whether it's routine maintenance or something more specialized, you can trust them to get it right the first time. It's rare to find a shop where quality, honesty, and expertise come together like this. Highly recommended you get your work done here!

    Hands down the best experience I've had with any automotive shop, period. I first came across Best Motor Werks on Instagram a couple years before I even owned my E90 M3. I bought my car and started noticing a few symptoms that clearly needed attention. A buddy of mine recommended I reach out to Nas. When I first called, I asked about a full inspection and told him I was happy to pay for a diagnostic. Instead, Nas offered to knock out the oil change I already needed and give the car a full look-over during that process, saving me money right off the bat without me even asking. We ended up agreeing to tackle the rod bearings, motor mounts, differential bushings, and the oil change. Not only was the turnaround incredibly fast (car was done within the same week), but Nas kept me updated throughout the entire process. He gave honest assessments, answered every single one of my (many) questions with patience, and never once made me feel like a burden. He even found that my oil pan was missing a few bolts, replaced the hardware, re-threaded two, and only charged me for one. No nickel-and-diming, just solid, honest work. It's rare to find someone who is not only incredibly knowledgeable about the platform, but also professional, communicative, and trustworthy. There's still plenty of work my M3 needs, and I can't see myself bringing it anywhere else. If you care about your BMW and want peace of mind, Best Motor Werks is the place. Thank you again, Nas!

    Trustworthy! We all know how hard it is to find someone to work on our BMW's. I've taken my 3 cars to Best motor Werks and they've always been reasonable, honest and thorough. You're not going to find a better place for service or price on the area. Nas intakes care of you like family; you won't be disappointed. From routine maintenance to mods, they do it all.

    I have used Best Motor Works for all my repairs over the last 5 to 6 years they're always honest and they know what they're doing. Nas, Nader and the team at Best one of the last few good shops you can find he won't sell you anything that you don't need and will recommend proper repairs and quality parts. They are always very fair on the price.

    Originally I tried this shop out because it was the closest shop to me in a 20 mile radius. But ever since that first experience with them I don't take my car to anyone else. They are friendly and always go above and beyond with customer service. It's rare to find a shop that cares as much about your car as the owner does. If you need simple maintenance, troubleshooting a problem, or an engine build they got you. 10/10 would recommend

    Everything from wheels to engine they got me laced up

    Best Motowerks is truly in a league of their own. Whether you're driving a high-end performance machine or something more laid-back, their team treats every car with the same level of precision and care. The staff is insanely helpful always going above and beyond to explain what's going on, offer options, and make sure you're taken care of. They specialize in specific sports cars, and my F80 M3 has been in their hands for years now. Every visit has been nothing short of exceptional. From routine maintenance to performance upgrades, they've delivered consistently great work and unmatched attention to detail. I wouldn't trust anyone else with my car. Highly recommend them if you want your vehicle in expert hands.

    I have a 1999 s15 imported from Japan and recently installed a nismo gt lsd from an amateur mechanic. Needless to say it was installed wrong. I took it to Nassar, he got me a great deal on the labor and properly installed the lsd. Will trust these guys for all my mechanical needs!

I appreciate the explanation of any issues he finds as well as images of the issue. I am happy to say that this is the place to come to for any mechanical needs! I am also glad my family is starting to come to him as well . Eddie! I appreciate you man! Thank you for the top notch customer service and amiability ! I truly value your knowledge in the automotive industry.

    My BMW M340i was leaking oil badly to the point my vehicle popped a notification to stop the car…read moreimmediately. In pure panic mode, I pulled over to call AAA. Eddie, the son's owner was willing to stay after hours to wait for my car to be dropped in their garage. AAA took over 2.5hrs to get to the garage, I dropped the key in the slot. He came to the garage early in the following morning to inspect my car. He ordered the part and charged me under $1500, which was just amazing! I wasn't from Upland, had to pay for a hotel, pay for my food and my lfyt rides to get an around. So they helped me out so much (I'm tearing up just writing this) Upon speaking to his Dad, I found out Eddie works on his whole families vehicles.. from Benz to Beemers. That his Dad is proud of what he has built and even more proud of the type of mechanic (little) Eddie is. That they believe in customer service versus charging customers ridiculous prices. I live in San Diego California. I have no issues of having my vehicle towed to Enzo's garage to have any future work done on my vehicle. I am a customer for life and I'm telling the world!

    ONE OF THE MECHANICS TRIED TO FIGHT ME! First off, The owner is a nice man, I hold no personal…read moreissues with him. HOWEVER, I brought my car to their shop initially for a rotor and brake pad replacement. I picked up my car and only a few days later the car started making grinding noises. I took it back to them and they assured me that the brakes were fine. No issues. But the car continued to make noise. So I had them replace the wheel bearings because I thought this was the issue. Still the car was grinding. I finally took it back and asked them to look at it. They said "you must've bought cheap parts off Amazon" because my wheel bearing was busted again. In only a month. Well I was upset and stormed out and said "whatever man" because I was not getting the proper help and one of the mechanics followed me to my car and shouted at me "You GOT A PROBLEM WITH ME?!?" and he stood in front of my driver's side door and gestured at me to fight him. It was a scary and insane experience. The owner called me and apologized for the employees behavior which I appreciate but that was all. He then told me maybe I need an alignment. Well, the grinding continued and only got worse. So I took my car to Firestone auto care. They found the issue. They told me that the driver's side rotor wasnt properly tightened and they were surprised the wheel didn't completely come off. So the initial rotor and brake replacement I had done at Martinez and sons was the issue and when I took it back because of the grinding they simply told me "No, nothing wrong with the brakes. Everything looks good. I doubt they even pulled the brakes off because how do you not notice the rotor isn't properly tightened down. And because of this, many other things were damaged. I had to get resurfaced rotors, new brake pads, new wheel hub and bearings. In total I had to pay 1,400 dollars but now the car actually drives great. This is on top of the initial 900 I spent at Martinez and sons trying to fix THEIR issue which they didn't catch. I no longer recommend this place to anyone after everything I went through with them.
