Engine repair service near Centerville, OH

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.

Outstanding professional mechanics. Saved me a bunch of money on a used car purchase. The car looked good, but had numerous mechanical issues that were not readily identifiable. But the Pit Stop crew identified the problems to me and advised I stay away from the deal. If not for them I would have purchased the car and ended up spending thousands to fix.

At this time we do not do air conditioning, transmission repair or RV Service at this location. We do offer RV service at the family owned location in Xenia, OH.

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!
