This place is odd... First off they have reviews that seem to good to be true. I received a business card on my Passat while grocery shopping, and actually, I almost threw it away! I then decided that I would let the inner gear-head in me do a quick check online. The reviews were all eerily positive. So i was naturally skeptical. I then checked their website out (www.fluidmotorunion.com) and saw their blog. Wow, how had i not known that a world class performance company was minutes away from my work? In house fabrication and custom ecu mapping was showcased on the pages and pages I read through. Ford, Nissan, BMW, and Lamborghini were just some of the vehicles I read about. Domestics, Asian, classics and specializing in European, these guys appeared to work on everything! Well as much as the performance interests me, I just don't have the money to put into making my car go faster, I just need it to run reliably. I recently moved back to the chicagoland area and have always been hesitant of the dealership. I was still hesitant at this point because i just didn't think a reputable performance shop would be good at repairs, the two just don't seem like they go together. I was still curious, so i called for a quote on some small issues i believed i had going on. The woman on the phone was very polite, but told me she couldn't give a quote over the phone. To me this seemed like the first warning sign that i should stay away, but as it turned out i was wrong. She stated that we don't charge to take a quick look at your car, and we will let you know what you actually need. Still a bit apprehensive about going, and quite frankly intimidated by the whole performance thing, I finally worked up the courage to go in. Again, Wow, the place was packed with high end vehicles outside and people were moving in and out and workers were dashing in between buildings, it was amazing! I walked in and was greeted by Marilynn, who took my keys and car concerns and they were off to work. I will admit i was a bit bored, no cable TV, and i forgot my laptop to take advantage of the wireless. I was getting an oil change and some issues i was having checked out. It took a very long time to do an oil change and i was just about getting irritated, when Marilynn came to me with a list of things that i would need to get done in the future with them itemized in order of importance. They told me there were things wrong, but not to worry, and gave me a time frame of 6 months before i should worry. I was even taken on a tour of the facility's and got to meet OJ, one of the owners, who advised me on the state of my car and some possible upgrades to do. The place has a full fab shop with some of the most unbelievable projects going on, its wild! They didn't charge me extra for the diagnosis as they give an hour diagnosis for free with the oil change, and they even cleaned out my interior and engine bay as if it was detailed. THIS PLACE IS ALMOST UNBELIEVABLE! Great pricing, great techs and its a fun place to go just to check out. I don't normally write this much about anything but I really want this place to succeed! Again do not hesitate to go here you will be satisfied and you will tell a friend, and you will be a believer! read more

Positive: Professionalism, Punctuality, Quality, Value Wonderful experience. I reached out to Fluid MotorUnion to seek help In fulfilling my life long dream to own a proper E39 BMW M5. First I sourced a fair to good quality unit sight unseen from an online auction platform. The vehicle was located in Canada during a pandemic at the time. Touched base with Marilyn at fluid motor Union to set up a plan. Her team was very happy to help in the process. Second I set up shipping of the vehicle directly from Canada to FMU for a full inspection. OJ and his team at FMU not only are master technicians and great people, the team at Fluid MotorUnion are automotive enthusiasts. They dug deep into my E39 BMW M5 as they inspected the vehicle, which every vehicle that receives a basic oil change receives this same thorough inspection. And we set up a plan to have everything that they recommended serviced to have a happy car. While giving a few optional goodies to add on to the unit to make it individually mine and how I wanted it, as an OEM + spec M5. FMU is ahead of the automotive scheduled maintenance, all manufacturers warranty repair work, individualism and custom fabrication industry. Once you make your first contact with Fluid Motor Union you are treated like family, better yet you are now part of the Union. They will go over any questions and present many options that will be in any budget that one may have in mind. FMU also offers online, text based scheduling system that is great. With online links to all your inspections and service recommendations with bills of lading and photos and videos of service being performed or a part that may need to be replaced in near future. as well as in person or over the phone for your custom fabrication and individual needs. As a over the road truck driver I wanted FMU in charge of this task because I knew I could trust them and as enthusiasts they would properly handle what I was looking for with my dream project and they over delivered. As I'm almost never home they went above and beyond to cater to my service needs when I was available as we worked together as a team to have my now dream car in better than new condition at home with me forever. Looking forward doing business with Fluid Motor Union for many years to come. Thank you again Marilyn ,OJ, and Donny you and your team are the best.

Marilynn & Team continues to do great work for myself and my family. The Team serviced my Dad's car which wasn't run in over a year and they brought it back to life, while identifying all the issues required. The difference between FMU and the Dealerships is that they take the time to do the root cause analysis, pics to establish confidence and competitive pricing. I've taken several of my Mercedes many times to the dealership, though they are top notch, everything is always replaced without the understanding of, "should it be replaced" or "can I get some more life till my next service"; this is the difference. Our dollars are important and the value of a product is important. Use the parts or fluids if it does not compromise the vehicle. Again, the Team took care of my Dad in more ways than one and we are pleased with the attention to detail and friendly relationship which we have developed.

I want to start with a huge thank you to Fluid Motor Union. I first met Marilynn a couple of weeks when I stopped in to make an appointment. (A must!) Marilynn opened up her calendar and found an open spot for my Tiguan. My vehicle went in for noise coming from the front. The team at FMU detailed their finding during the inspection and provided images. I have spoken to Marilynn multiple times during the two days my vehicle was there. The noise I was hearing was hard to duplicate. She then mentioned that OJ pinpointed what I was hearing. Overall they went beyond to make sure that I was satisfied. I've had this vehicle from day 1 and now at 99k miles, I know what noises are typical and what needs attention. Fluid Motor Union is NOT the stereotypical repair facility that wants you in and out. They listen to their customers and give 110% to assure you are satisfied. When it was time to reconcile, Marilynn said no charge. In my 30-plus years of taking vehicles in for inspections/ service, I NEVER had such news. If you need work done don't hesitate to give them a call or stop in to discuss your concerns. I drive two VWs, and this is my go-to shop. Thanks again. Happy Thanksgiving! read more

Fluid is the most honest car shop I have ever been to!!! I came in after getting a quote from the dealer. They told me that I didn't need my breaks changed yet and exactly how long I had left on them! They didn't even charge me a diagnosis fee since I did get it serviced there. There diagnosis is top notch and these guys really know what they are doing. I had a problem going on with my car and I took it to about 5 different shops and they were all stumped. The reception was also very nice and treated me like family. I got a tour of the shop and they have some mind blowing things going on. I would highly recommend it to performace freaks as all their work and welding reeks of quality. I felt confident after seeing all the high end cars in the parking lot...Mercedes Benz, BMW, Audi, Lambo, etc. but what really impressed me was the technician's willingness to talk to me and explain what was going on with my car. It was kind of cool to learn something while I was there. Try them out...I will never go anywhere else!!! read more

This place is bullshit. Don't know if it was because I was white why I received such poor service and attention or if they just screwed me for personal reasons. Regardless, stay away from this place if you don't feel like being a repeat customer from falling into their scam. Mediocre work with nothing to back up anything they claim about their employees. Any articles you read about their cars are in fact owned by them or their friends. As for the scam, they will put codes in your computer to throw lights so you have to service your car more often as well as do intentional damage trying to get as much cash out of you as possible. Any positive feedback is from friends or family members as you will not find one legitimate feedback from someone they personally don't know. The woman running the shop knows nothing about cars, repair, or customer service. Was also harassed on a website they sponsor after having the problems I went through after making the mistake of taking my car there in the first place. read more

If you live in Naperville or are in the outlying western suburbs, and you are having problems with your European vehicles and or just want to give it a look that sets it apart from all those other Chelsea Tractors out there. Then Fluid MotorUnion is the right RX for your vehicle. OJ and his staff are second to none in knowledge and support. They have a great waiting area with a big screen TV, DVD's, XBOX, Games, and loads of magazines. All of which to keep you busy as well as the wife and kids, while your baby is getting a check up in the garage. Now my wife's grocery getter is tip top, and I would even take it out for a joyride every now and then. If you don't want to spend big bucks @ Perillo or Bill Jacobs and not get service with a smile. Then go to Fluid MotorUnion, get exceptional service, a smile, knowledge, and a bit of class for your vehicle! I can't remember the last time i was looking forward to having a repair or custom work done on a vehicle. However, this place fits the bill. read more

I was pleasently surprised at the service this place gave. Everyone knows their stuff here and I loved that they went over every detail of what work needs to be done and why. I was also happy that they were willing to work with me and gave me great advice on what work needs to be done and what I can wait on. They didnt try to upsell me which is hard to see these days. They seem to be very passionate about their work and it shows with the kind of work they did on my car. The place is also equipped with everything to make ur stay enjoyable. They had an xbox and a bunch of games I could play as well! Not only that they had a desk for me and free wifi so I can work right there while I waited. I hope I dont have to keep getting my car fixed but if I do this will be the place. read more

The team at Fluid Form Union did an outstanding job working on my truck. They were very thorough and took the time to explain everything clearly, making sure I understood the work and what my truck needed. They were knowledgeable, helpful, and happy to answer all my questions. They also took pictures and provided a detailed, well-written report, which helped me understand their findings and recommendations. I really appreciated that level of documentation, attention to detail, and communication. It's reassuring to find mechanics who take pride in their work and keep their customers informed. I highly recommend Fluid Form Union to anyone looking for quality work and excellent service! read more

We have been customers of FMU for over eight years and had four of our German vehicles serviced there religiously. I'll echo all the comments regarding fair price and knowledgable staff but even more important is the EXCEPTIONAL customer service. Case in point - I recently had a panic situation requiring emergency work on a Saturday afternoon. Without hesitation OJ and Marilyn invited me to the garage and immediately proceeded working on my car. The shop closed at noon, yet work continued for nearly two hours into their afternoon until the issue was remedied. FMU is the reason my 11 yo BMW runs like a clock at 200,000K! Bravo!! read more

Tried replacing back brakes on my 328i on my own but wheels were seized to the hubs. Contacted Mike M. via e-mail and set up appointment. Brought parts I had purchased on my own and they used them without issue. Car was fixed incredibly quick and Chris was pleasant to work with. Only issue was that like Gerry H. said, I was pretty much ignored while I was waiting to pick up my car even though someone was stationed at the front desk. Regardless, I would bring my car back to FMU without question. Good prices and their website shows they are skilled craftsmen. read more

I just had my front bumper resprayed on my Porsche Cayenne Turbo and I'm thrilled with how it turned out. I have been told that silver is hard to match but it's perfectly blended color wise with the hood and fenders. Also, I they really went the extra mile replacing two bulbs and diagnosing and tightening a suspension component free of charge (I just paid for the bulbs). Fluid MotorUnion will be my one stop shop for maintenance and upgrades going forward. Thanks again guys! Al read more

I took my Mercedes CLK550 in for a brake job, and then left it with them for evaluation on a little hot-rodding. Fluid has great experienced techs for repairs, and can test and tune anything with wheels. They have a dyno facility, cnc machining center, and Craig's fabrication skills are awesome. Whether you need simple repairs and maintenance, whether it's a toyota or Lamborghini, these guys are reasonably priced and skilled techs. Say hi to Marilyn for me while you're there. read more

Just took my mom's mercedes into the shop. The car was in limp mode and not moving. These guys were deeply concerned and helped me get it back on the road without it costing an arm and a leg. The boys cleaned up the module that filled with oil, cleaned it out and refilled the fluids. They could have charged me thousands but charged me for what was needed and what they did. Real honest guys. I will continue to send them business. Thanks again guys! read more

This company is horrible and don't believe anything good you hear as they have an internet team posting false reviews just to get in your pockets. These guys are a bunch of young hacks who really don't know anything when it comes to cars except how to bolt pieces on which anyone with a tool set from sears can install. Take my advise and head to a REAL shop if you don't want to regret them screwing up your car. read more

This place only receive's good comments by people their it team or by their friends. this place is a scam and i believe they purposely messed up my vehicle with the minimal work. They have bought all their coverage as the rest of the aftermarket car world trying to make a business out of money. I get it, it takes money to make money but they seem to pick and choose who they do work for. STAY AWAY FROM HERE. read more

These guys are the best. They are by far the most knowledgeable and honest mechanics I have ever dealt with. OJ was extremely professional and was able to figure out an idle issue with my car that no other shop has been able to figure out. They work on any and every type of vehicle, any type of job. I won't bring my vehicles anywhere else from on! read more

I'm very happy with Fluid MotorUnion. Turns out they not only work on high-end imports, but they successfully removed the spark plugs out of my 2004 Ford F-150. Might not sound difficult...but they are notorious for breaking in the engine. I'm not a mechanic, but that sounds like it would be expensive! Thanks Fluid MotorUnion! read more

Following a Valet mishandling my car Fluid MotorUnion quickly determined what was wrong - recharged and reset the entire system at no charge. They were so respectful and kind! Clearly they are experts and genuinely good people! They will have all of my car maintenance business from now on. Thanks again Fluid MotorUnion! read more
