Can’t believe there are no reviews on here. I just moved to LA and wanted a second opinion on why my check engine light was on. The guy from Jeep had told me it was probably my catalytic converter and was gonna cost me about $ 1700. I called Jeff at Signature and went the next day. He ran a diagnostic on it and put some Marvel Oil in the gas tank, turned off the light and told me to fill up a half tank with some good gas, ie. not Arco! And come back to him. It’s fixed, he expected it to be something smaller but actually it turned out it was as simple as the fuel line just being clogged up with crappy gas! I’m SO thrilled that I didn’t listen to the first opinion, and pay a fortune for something that wasn’t even wrong. I saved literally hundreds of dollars and I now have my forever mechanic in LA. Highly highly recommend going here if you want an honest, decent mechanic who treats you well and respects your custom…
