    Jim Simpson first started his career as a certified mechanic in 1973 working for a BMW dealership. He later moved to North Carolina in 1977 and worked for a race team known as Korman Autoworks where he worked as a crew chief and mechanic. After gaining experience in the racing industry Jim moved back to Iowa City in 1980.

    Jim has an impressive list of BMWs he has owned, with over 12 different types of BMWs from 1600s to M5s. Jim's racing background is just as impressive as his BMW ownership, he has been racing cars and go karts since 1973 and even raced Moto Cross for 18 years.

  • Take my E30s here, great BMW service.

  • Simpson Motorsports is without a doubt the BEST place to have your BMW maintained, repaired, or performance modified. Jim Simpson (the owner) has over 30 years experience working EXCLUSIVELY on BMW autos. He and his son Tim Simpson provide extremely meticulous high quality service, which is performed at 30%-50% less than Iowa BMW dealership prices. No Starbucks or popcorn, but when you turn on to I-80 or I-380 you'll be smiling ear-to-ear. Absolutely THE BEST BMW service in Iowa, period.

    Simpson Motorsports repaired the clutch, rear window, and did a major inspection on my 2000 M Roadster. Professional and quick. Very happy with the quality work they did. Highly recommended.

    The issue was about a wiring problem which was making my trunk lid to not open. Jim, Paul and Tim at this pretty neat workshop handled the case professionally and made it very transparent. These guys only do BMWs and know the cars well. Got to try them out. They are small in their costs and big in delivery! Thank you Simpson Motorsport.

    My wife's 330i cooling system failed catastrophically. Simpson Motorsport had it diagnosed and repaired for a reasonable price very quickly. They are the BMW shop to go to in the Eastern Iowa area. Quick, professional, and experienced.

    I drove my E36 M3 from Omaha, NE to Simpson Motorsport to have a TC Kline suspension put on the car, which Tim did quickly for a great rate. He even stayed a little late to finish up the job and explain how to adjust it. However, as I was leaving Iowa City to head back home, I was rear-ended. Not knowing where to go, I had the car towed back to Simpson Motorsport. Tim had already left, but out of sheer luck, Tim happened to return to the shop as I was getting ready to call a cab and find a hotel. He opened the shop back and put the car on a lift so we could see what kind of damage there was. Luckily, it was mostly cosmetic but there would be a few items that had to be addressed before the car could be driven back home. As it was already 9pm, Tim gave me a ride to my hotel that night. The next day, Tim spent the morning helping me get the car ready to drive back home. He really went above and beyond the call to help me.

    I 100% trust Simpson Motorsport with my cars. Tim and his father are very honest, as they try to get you the best pricing on all parts and labor. On top of that, they really know BMWs well so you know you are getting the best quality service. Even though it’s a 4 hour drive from Omaha, I will be bringing my pair of M3’s back to Simpson Motorsport whenever possible.
