I can't say enough good things about Fluid Union Motor! My car had a frustrating intermittent starting issue that turned out to be much more complicated than expected. Leave it to the professionals at Fluid Union to actually dig in, figure out what was going on, and FIX it! They were thorough, knowledgeable, and persistent in diagnosing an issue that definitely wasn't an easy one. Marilyn, the office manager, is also such a joy to work with! She kept me updated throughout the entire process, answered my questions, and made sure I always knew what was going on. It's such a relief to have my car working properly again and to know I have a shop I can trust. Great people, great communication, and most importantly, they know what they're doing! Highly recommend Fluid Union Motor! read more

I hired FMU for a pre purchase inspection on a lamborghini aventador. I buy cars maybe about 1-2 times a year from all over the country, and I did not have a PPI shop in the Chicago area. The lambo dealers declined the PPI request, and so I was looking around on google and found FMU. Impressed by their number of reviews and caliber of cars they take in, I decided to give them a ring. Impeccable customer service, attention to detail, very responsive and reasonable rates, probably among the best of the PPI shops I have used. During initial phone consultation, they are very responsive to my questions and flexible on schedule. I request the car sit overnight so the tech can go over it during cold start in the morning, as that's usually when issues come up sometimes. I went through the things that I want them to pay attention to, they took it down and I had the tow truck scheduled. After delivery, they take a look over the car and took a lot of pictures on the cosmetic inspections. There were some cosmetic issues so they actually called to show me the pictures first, to see if that's something they should continue to work on, should i want to stop. I was never offered that option by any previous shops, goes to show how honest and genuinely helpful these guys are. I told them to go ahead as the issues are still somewhat acceptable. Over the next few hours, they went through the car in detail and pictures and description kept coming through the inspection app/link. The car had some immediate issues that require fixing, and these guys caught all the big ticket items such as leaking shocks and ac compressor. In the meantime, they are very communicative and the car sat on the lift, so if I have any additional questions they are available to go back and take a look. Even after the report is generated, they still spent the time to research and provide an estimate on all the deficiencies noted on the car with an invoice, which i can present to the dealer. It also helps me gauge the overall cost to purchase this car, and helps in making an informed decision on whether it's a good buy or not. They seem knowledgeable around these v12s which is hard to come by, and it's actually a great convenience to have them service or repair the cars before it gets shipped to me. Their rates are fair (certainly comparing to rates in California) and these guys work hard and are honest. You can always tell when a shop does very minimal work on PPIs and try to BS you a piece of paper with no pictures and a quick phone call, from my bad past experiences, which usually led to cars that i regretted buying and soon have to get rid of within months. Not FMU, this will be my spot for PPI and services in the Chicago area. read more

Simply the best! I've had all my supercars serviced there and they were always professional, honest, and accommodating. I enjoy their customer service! read more

I've been bringing my 2016 BMW 550 here for years, these guys are the best they don't mess around and try to sell you something you don't need, they are honest and tell you when parts in your car are perfectly fine even though the dealership is telling you to replace them. They've never been wrong. They honor their warranty on all labor without question. They treat me the same in my nine-year-old BMW as the guy with a two year-old Lamborghini. Always respect always kindness. read more

Fluid knows foreign cars. Great to work with. Reasonably priced, great service and convenient location.

Mechanics are good, management is not. If you like paying obscure fees, then you'll like it here. I had a 99$ fee for shop supplies, when the work was just diagnosis at that point. Also, a $120 fee to use the Mercedes online catalog(not sure why that's passed down to the customer) They never gave me the deposit for the catalytic converter, which even dealerships do. They also said they don't make money on the "labor" at $220 an hour, which is why they don't discount parts, and won't let you bring in parts, when clearly you can buy it for 30% less online. read more

Always fix my vehicles correctly the first time. Marilyn is great to work with!!! Prices are at a very rate.

Exceptional service. Been going to Marilyn and the team for over 7 years now and spanning almost a dozen cars. They are remarkable in every way- problem solving, planning, quality of work, and fair pricing. It would be hard to beat these guys! read more

I called with short notice to get some work done on my R8. I had almost immediate responses from Donny and Marilynn who tried to find a way to fit me in before I had to take my car out of state. They ended up getting everything done in time and @ better pricing than the dealer. They were suprisingly communicative and professional through out and I would not hesitate to go back or to refer them to anyone in need of work on their car. read more

The folks at Fluid MotorUnion are awesome! I was prepping my '16 BMW for a road trip and took it to a local dealer for some service and a look over. After a few recommendations from the service advisor, I got worried. Rather than servicing at the dealer, I called the team at Fluid MotorUnion and they worked to get me in the next morning! They did an extremely thorough review of the car and provided clear recommendations and offered options on what needed to be done now, watched over the next few months, and things to keep in mind for my next service interval. Its clear their team has a wide range of skills, what the MFR recommends, and knows what is required to keep cars (exotics, performance, and daily drivers) running their best. I left the shop with a detailed report, including pictures and feeling confident that my car was ready to rock and that I wasn't being over sold. I look forward doing business with Fluid Motor Union for many years to come. Thank you again OJ and Marilyn - your team is the best. read more

Would never take my car here ever again. I feel like they took my money and they didn't do the exhaust like I I wanted them to do it. We talked about having muffler and the have a cutout to buy pass the muffler. When I pick up the car they completely did something else. Instead of muffler they put resonators and didn't even put cutout. I was looking under the car and found two exhaust leaks where they didn't put gaskets. If your looking to get a custom exhaust I would look some where else. read more

Took my car for an oil change and they did a great job and they were very fast. one of my biggest fears is how places handle your car behind the scenes. the nice thing about the shop beside the very very comfortable lounge area is you can see the whole shop and then working on your car. I could see they took extra care of the car. Also they gave a comprehensive list on everything they checked on the car and what to look for in the future. I will definitely be using them as my go to place for my BMW M3 CS. read more

Best place to take your exoti-car and/or daily driver for honest, supremely competent service/repair. They've kept my 300,000+ mile Benz running right without breaking my budget. Marilyn and the staff are the best. read more

Awsome service, clean facility. Expert technicians, I would highly recommend to anyone looking for worry free services.

I couldn't find anyone in the Chicago-land area to install a set of Eibach springs on my 2022 BMW. Places either didn't want to install aftermarket parts or wanted me to purchase the parts directly from them. Most places simply didn't respond to my inquiry. Not FMU. FMU quickly responded to my email request, scheduled me, and completed the work with great quality and ahead of schedule. Even though my BMW was like a Yugo in a sea of exotics, they treated me like a VIP. Yes, they are a little pricey, but there's value in knowing the work was performed by true pros who stand behind their work! read more

First of all, Fluid Luxury Care is repair shop of excellence, and all foreign cars need to go here. My 2015 BMW 528 stopped and it was towed there. Marilyn and the entire staff communication was excellent. The BMW dealership is ridiculous and did not care. Fluid provided a fair price and fixed the problem. The inspection report was detailed with all the information I needed with pictures. I travel a lot and having my car working is vital. By the way, shop was clean. I will only take my BMW here. They are the masters. Thank you for everything! The Johnsons read more

Can't thank these guys enough for making my Urus sound soooo good with their custom exhaust system!

I cannot say enough great things about this facility! The staff was amazing to work with and I would strongly recommend this auto shop to anyone looking for a German car repair facility in Naperville area. read more

These guys are incredible. I brought my McLaren 720s in for a stage one tune and an oil change. They provided me with a comprehensive evaluation of all the inspection points they performed and it made me feel good that the car was in good hands. The oil change was 1/3 the price the dealer wanted to charge me. And the tune is ridiculous. The car runs so smooth and is so much faster now. I couldn't be happier with my experience with Fluid Motor Union. I'll be taking my all my cars there from here in out. read more

If you've taken even the slightest gander at Fluid Motor Union's website, reviews or social media, one thing will be apparent to you - supercar owners trust this shop with millions of dollars worth of valuable gems. If you visit Fluid Motor Union for your vehicle, no matter how ordinary it may be, you will quickly understand why. Fluid Motor Union is a well respected and recognized tuner whose technique can extract almost magical amounts of fun from your vehicle. I have been taking all of my cars to Fluid Motor Union for fun extraction as well as regular maintenance for quite some time now. To me, Fluid Motor Union excels in three critical areas of an automotive repair business: 1.) They communicate clearly, honestly and with respect to your time and resources. I typically work with Chris who invests the time and energy to clearly explain my options, the cost, and process involved in the work being done to my vehicle. I could not be more grateful as communication is key to building trust. 2.) They respect your time and remain flexible in the logistics of your repair. Alternative transportation is not always easy to secure nor is last minute breakdowns avoidable when you own German luxury cars. Fluid Motor Union has never intruded on my life and remained complimentary to my schedule and the schedule of my vehicles. 3.) They are a personable local business with the knowledge and expertise of a world-class tuner. The results at Fluid are undeniably the best you will find in Chicago. What sets them apart, however, is the fact that when working with them you always feel like a member of the family. Fluid Motor Union is my first and last choice for maintenance on all of my vehicles. I could not be more grateful for the work they have done and the work that they will do in the future. I highly recommend their services to anyone in need of automotive related work whether you drive a Toyota Prius or Lamborghini. read more

So i purchased a 2012 Fisker Karma from Las Vegas ! This first week i got it ... the AC stopped working then it leaked antifreeze ... i freaked out because there's no Fisker dealership in Chicago :( . The nearest location was in Troy Michigan ?!?! Lol!!! Luckily my friend who owned a Fisker referred me to a technician that used to work on his car. Thankkkkkkk goddddd this mechanic happed to work 10 minutes from where my car broke down! I was a little worried at first because i saw so many nice cars at this place. I asked if i can buy my own parts and Chris the service advisor said sorry we order parts. I was a little confused but i understand where they're coming from because people sometimes order the wrong parts etc or if the part breaks then they blame the shop . I told Chris i just don't want to over pay on parts etc. he said don't worry we are very fair over here. I can definitely see why they are always packed . Honest business and they were very reasonable with the repairs and they saved me a tow to Troy Michigan hahaha . They even had the software and scanners to update my software on my car. I will be bringing all my toys over here. read more

Stand up guys and techs...they are well versed in the exotic car segment. Had them install some KW's on my 93 NSX and i was very pleased. Communication skills are superb. Dropped my car off on Saturday morning and had it back by Tuesday as scheduled. Service - I was pleased with the level of communication i received here. There were certain height requirements i had and due to work I couldnt go back and forth. I was continuously updated via pics and phone calls for assurance. We went back and forth a few times before agreeing on something and when I saw it in person it was perfect! Price - Depends on what you compare it to. You can probably get the same install done at another shop for 1/2 of what i spent, but do you want to? Shop is well kept, guys keep the cars clean and respect your needs. I know i couldve gotten a better price but the peace of mind and comfort in knowing these guys are taking care of my car as if its their own is worth something to me as well. Overall - This place is eye candy. I saw cars here worth 2/3 x's as much as mine. You can walk around for a decent hour just admiring/drooling over every car around you. The lady in the front, Maryland I believe, is very kind and sweet as well. If you want a peace of mind and have the work order done properly the 1st in an efficient matter stop looking elsewhere, pay the premium and get it done here. Gotta pay to play as they say. read more

Another great experience with Fluid MotorUnion! I've been working with FMU for over a decade. They've serviced my BMW M3, Mercedes E550, Jeep Wrangler Sahara and Toyota Sequoia. I specifically started going to FMU due to their expertise working on German vehicles; but found that they were always extremely honest, specifically regarding work and/or scheduled services that needed to be completed or weren't necessary. Have recommended to several friends who have Mercedes and BMW's and nothing but positive experiences with FMU. Highly recommend FMU! read more

Great place to have your BMW (or any make for that matter) serviced. Rates are lower than what Bill Jacobs quoted me. Everyone is friendly and informative and the waiting area is nice and clean. It is a much larger facility than I was expecting, great place. read more

My car had hit a curb and needed an alignment. I called and scheduled an appointment for the very next day. The facility is top notch with best customer service. I don't have a Ferrari or the Lamborghinis that they usually work on but they treated my car just as such. Quick turn around and not over charged like many other mechanical locations. I can't recommend fluid more than I already do. Go to them and they will take care of you like you're royalty. read more

Only had a simple oil change performed, but the staff was friendly, cordial, and they performed the work at a fraction of what the dealership would've charged me for the same service! I will be returning to FMU for all my cars future needs. read more

Let me shout it out.... Fluid MotorUnion is where you should go for maintenance / repair of your foreign auto. I live in the city of Chicago and have been taken advantage for years. Everyone knows it but what other option did we have? NONE, not anymore! I was told by an "inside source" in the maintenance / repair industry.......go to Fluid. This group is the best in the area, possibly the states and will repair / maintain your car with no mistakes and won't break the bank. That's all I needed and I got my map quest and left the city. A little over 30 miles west of downtown Chicago and I have found an honest, maintenance / repair group of professionals for European autos. They do more a lot more. They customize high performance cars and do things with performance issues way beyond my comprehension. This is what I know a sensor for my BMW in the city was $80 plus 15 minutes of labor. At Fluid the same sensor cost $18. The light bulb for my front headlight (xenon) was over $350 in the city and less than $100 at Fluid MotorUnion. The list goes on and on just concerning price differences. BUT the biggest difference is their expertise and honesty. A cohesive group of knowledgeable honest professionals that thrive at perfecting their craft. Where do you find that! Make the change, Fluid MotorUnion is a destination for European car issues, Kim Korber -- Kim Korber, CIPS @properties read more

Poor customer service and lack of professionalism. Lack of communication regarding what was performed and the cost. Waited many hours and was never informed of additional "work" and was charged at the end more than what I was advised. Not happy with the lack of communication, the cost and services. Would definitely look elsewhere for better overall care. Agree with Greg's post on 8/16/18 read more

Very unprofessional and do sloppy work. The lady named Marilyn operates the place. Had work done on car and had problems the next day. Do not patronize. read more

This shop is phenomenal. This was the first time I've needed to take my Volvo in for some work and having moved up here from Texas not too long ago, I spent quite some time doing my research. Not every auto shop can work on European vehicles much less do a proper job, so my search was fairly limited. I settled for this shop and was ever so glad I did. Chris was knowledgeable and responded to each of my emails promptly and professionally. When I dropped off my vehicle, they started on it right away. On my return, Chris went over everything that was done and didn't push for any other unnecessary work. He merely discussed what he recommended was needed to be done later on based upon his inspection. As I got into my vehicle, I found that it had been vacuumed without my asking! There was also a card with a lottery scratch off thanking me for being their customer as well. First time any business as ever given me the kind of personal attention like what I received from Fluid Motorunion. I believe I've found my go-to mechanic shop! read more

I'm a female with an older Acura that I love, but am always cautious when having work done on my car. I've been taking my car to Fluid for years, and have never felt ripped off or taken advantage of by them. This place is legitimately honest. There have been times when I've thought that something was wrong with my car, they identified the described problem and explained that it wasn't anything I should be worried about. Other times, my car has needed a lot of work. Repairs are completed in a timely manner using good quality parts, and estimates are accurate so you know what the amount is upfront. Prices are reasonably in-line with, and often below, national averages or quotes from other auto shops. Additionally, the same people have been working here for years so there really isn't confusion or a high turnover rate. They know who their clients are when they call in and are always helpful. The team at Fluid always takes time to answer my questions and explain what work needs to be completed and why. They don't try to up-sell me on unnecessary work and if a repair can wait until a later date, they tell me that too. Fluid has helped me out numerous times throughout the past few years and because of their great service and quality work, I happily drive to from Wheaton to their shop in Plainfield. read more

I have been taking my car to FMU for the last 10 years. They have a very talented team that can handle simple oil changes / fluid flushes to more advanced engine and transmission repairs. Additionally, they do kickass work on custom modifications and enhancements (like exhausts, engines, etc.) . If you have a foreign car (which FMU is very experienced with) or a domestic car you will be in good hands with them. Service is very top-notch and ricing is very competitive. FMU will be very honest with you in terms of what needs to be done, what should be done, or what is a nice to have. read more

Fluid MotorUnion....let's just say that you will not be disappointed in the prices and amazing customer service offered here. I just recently got my Gallardo serviced and inspected and I payed a fraction of what it would have cost me anywhere else. This is the place I will always go to for ANY work on my cars. read more

Quick and reasonable pricing for an alignment. Friendly staff. They did a good job with the alignment.

I came to Fluid MotorUnion to get new brakes after the dealership told me I needed them. I'm glad I stopped in b/c they were honest with me and told me I did not in fact need new breaks and that I had at least another year left on my breaks before I needed them replaced. I left irritated that the dealership had wasted my time but happy to have found a trustworthy shop that I will be coming back to for routine maintenance. read more

Fluid MotorUnion provides first class service! I picked up my car on Wednesday after having service on my car. On Friday night, I started to have some issues. They paid for a tow truck to come to my house to get my car. Within an hour of getting my car, they had the car fixed and were so apologetic about it. They stand behind all of their work and everything is under warranty. Marilyn is wonderful and even offered to pick me up at my house so I could pick up my car at the shop. They are so professional and have great customer service! read more

To start off, I'm very meticulous to when it comes to servicing my vehicles. When I found out that I was advised to do a valve cover gasket set replacement, power steering fluid and coolant flush and fill I was in search for the best in the suburbs. I took time throughout the week to do an intensive research. Chris from Fluid MotorUnion (FMU) was able to keep in contact with me to schedule maintenance for my vehicle within a two days notice in which I came in for the service. A week later, my car has been sharp and enjoyable to drive again whenever I come home from the city in the weekends; terrific service! Chris and the crew at FMU is the best around! Thank you. read more

I had Fluid do a cv boot replacement on my F12. They communicated professionally and consistently throughout the process. They sent excellent videos of the inspection and repair since I live two hours away. Couldn't be happier with the service and pricing I received. read more

Love love love FMU! Just like the service from the dealer without all the BS and the high prices. All the mechanics are very professional and curtesy to the customers and with all my cars being maintained by this company. Unless it's under warranty by the dealer, I'll never stop coming here 10/10 read more

I just want to say... this shop, these guys (and especially Mom) are absolutely amazing! Honest , reliable and care about their customers. I take my Mercedes C300 there for any service or repair and always am treated like family. Our C300 is an extravagance for our and we are careful with what we can spend, but Fluid Motor Union is one of the most reasonably priced shops around. I recommend this group as often as I can - you will NEVER GO WRONG by taking your car to Fluid Motor Union!! read more
