-Tawnya P.

"I had an oil leak and I could have been taken advantage of very easily...but they were honest and told me it was a simple fix, and I walked out paying less than originally quoted. I understand every business has to make money to strive, but I can see they value their integrity over making a quick buck. They've gained my respect and future business. I highly recommend this company!"


-Roxanne R.

"I found this AG Automotive through yelp. So I decided to give it a try. I sent in one of our inventory (2006 Ford Crown Victoria Police Interceptor) in for steering wheel stiffness diagnostic. Owner Chuck was able to identify the problem in the first place. His crews are very professional (more professional I thought I was at a car dealership service department). Great experience throughout. Most importantly, got the job done right. They know what they're talking about. Certainly not some BS mom & pop shop just there for your money (if they fixed it right the first time). Price is fair. If you ever have problem with the repairs they done, there's always a warranty to back you up. Thank you chuck. I will be back at your shop for our other vehicle recondition. From: Ideal Motor Group in San Gabriel Valley."


-David L.

"I went here with a really bad brake problem. Chuck took the time to explain the cause of the issue and what could be done to not only fix it but how to prevent it in the future. He and his team are professional and highly knowledgeable. I feel confident and grateful to these guys. I definitely recommend this shop and will continue to refer friends and family here. His prices are more than fair and the work is top shelf."
