The team at Mraz replaced the transmission and clutch in my Mini Cooper (2003) in about a day. The longest wait was for parts from Mini USA, but they were able to have everything done very fast. The car came back spotless, and the price was much less than the dealer. They also accepted my extended dealer warrenty that I purchased when I bought my car with no problems.

Terrible experience, continuous brake noise post repairs. Do not trust, not resolution per Bob Lutter.

Service as great. Done when said and less than expected....it was a BMW!

Good work! Reasonable prices. Always updates you with changes in products and or cost. I inly rake my cars to him now.

They do a great job here. Come to them for all my car needs. Reliable, trustworthy, and affordable. Recommend them to anyone in the Milwaukee area! -Brittany Aceto

If you are in need of a great mechanic, Heppe's are your go-to guys. They made my 1996 Audi feel like I just drove it out of the showroom. Honest, good hard-working folks. Can't recommend them enough. I used to be a mechanic back in the day, but your average guy can't work on cars these days without expensive computers, etc. They truly know their stuff, are 1,000 times better than a dealer, and get the job done. They also did work on my wife's car many times and she's super happy. Give them a try. This is a 100% unsolicited review. I give them a 10-star rating!
