1 /5 Antoinette Imus: This address is at: 100 S. Hathaway St., Santa Ana, CA. 92701. This is a sister location but not any building. It is an outside yard enclosed by a fence. I brought my car here to diagnose an annoying chirping noise. The mechanic Carlos and the manager Marc diagnosed it to need a new cam shaft. They said it would cost $2,600. They also gave me quotes for some bodywork which were way overpriced! My husband did some research and found a YouTube video that said the chirping noise could be from the spark plugs not being torqued properly. So my husband fixed it by torquing the spark plugs properly. It never needed a new cam shaft for $2,600!!! They charged me $75 to diagnose the car. I asked for my money back and they said they would send it but never did. This business does not know how to diagnose problems and completely overcharges for issues that dont even need to be done. BEWARE!!!
