"I was looking for someone to work on my 1986 Corvette. It was running rough and I could not fix it myself. Contacted Chris the service writer and he couldn't of been more professional and nice and took me in the next day. Called me after 1 hour of working on it to give me a update. Told me exactly what it was and they fixed it plus more. Car is running 10x better now. They have my business forever. Owner was so nice and she was great too. THANKS AGAIN!"
"Thank you guys for the wonderful time. The service was exceptional and I will be returning next year or if I happen to need my car serviced for any reason. I'm glad I found a trustworthy auto shop in my area."
"The quality of work and customer service is top notch. Both times I have been in they offered advice and options to choose from with no sales pressure. While my SUV was in they inspected it and offered to fix any issues at a very reasonable price and offer assurances the SUV was otherwise in good working order. I will be taking my SUVs/Cars there from now on! Thanks OJ, Chris and the Fluid Motor Union Team!"
"I have been bringing my cars here for years for service and modifications and couldn't be happier. They do fast and thorough repair work when necessary with very reasonable pricing. I have brought an R8 and a Huracan to them for exhausts, both of which have been some of the best sounding exhausts my friends and I have ever heard. Power gains were definitely noticeable in lower gears which was a big plus! I highly recommend you take advantage of FMU's commitment to service and quality."
"I was referred to fluid by a fellow M owner a few years ago..bought a BMW 750 and was able to use them for the first time. .my experience was great..better pricing than a BMW dealer with same quality of work..very clean shop..and honesty...that's the biggest plus...with just purchasing the car used I wanted everything up to date..they were beyond honest and did nothing to the car that didn't need to be done...very happy with this company"
