Engine repair service near Evendale, 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.

Sooo helpful! Best mechanic around! Super affordable! Explained everything so clearly! This is the only mechanic I’ll use for now.

I love these people. They always take care of my cars and trucks. Very professional and no job is too small. I have recommended them to my neighbors and friends. Keep up the great work. Sandra Pierce
