Engine repair service near Miamisburg, 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.

Liberty Auto always does a great job, provides great service, and applies fair pricing! I would recommend Liberty Auto to everyone.
