High performance parts service near Dayton, OH

I brought my high mileage Mercedes here after it decided to not want to start. What is great about C's Autohaus is what they didn't do; they didn't try to take advantage of me because I'm a Mercedes owner, which up until now, I thought was some kind of code for moron to repair shops. I'm used to taking my car in to a shop and having them try to sell me thousands of dollars worth of useless repairs with highly inflated part costs. C's Autohaus was able to diagnose that it was just the starter motor, and replaced it at a responable price. They were also able to find and fix an oil leak the same day at, again, a reasonable price, and they fixed some minor performance issues while they were in there gratis. After those repairs my fuel economy went from about 10 l/100km to around 7 l/100km (smaller number is better). The shop itself is pretty cool too. They have a lot of old VWs from the 60s and 70s on their lot which I'm guessing are project cars.

Not all automotive shops will even attempt to repair a Cadillac. Called Jeff's, was given an immediate appointment and an immediate repair. How very professional and friendly this shop is. No wonder they have such a successful business. Not to mention the very reasonable cost of the repair. My Cadillac has a new doctor! Thank you Dana and all the guys!

All Speed Innovations aka Sigma Six Engineering is ran by a wanna be engineer named Pat Smith. Pat uses customer cars as his personal cars while in for service. They charged me for a alignment and the alignment wasn't done. They also took it to a alignment shop without my permission. When they installed plastic TGV deletes they connected a ground wire to them. Pat couldn't figure out how to connect his laptop to my car and disable the TGVs, I did this myself after reading how to do it on the Internet. They also built a cage for a customer and ruined the customers car. Everyone should stay away from this shop or anything related to what Pat Smith does.
