Smog test service near Vacaville, CA

We were on a trip to see family when our engine started over heating. We putted our way to the nearest high rated mechanic. As soon as the mechanic arrived we got a price quote, and promptly began working on our vehicle. The time went over what was estimated but the price did not. He was very thorough and explained everything that was happening with our vehicle. We liked the transparency when with the large bay window looking into the shop. We are extremely pleased with the service. If we lived in the area we would definitely make this our go to mechanic. Evan R.

I have already refereed another customer to you guys, you are straight forward and feel like you work for the little guy, not common for a lot of shops, especially a shop with a reputation such as yours.

I came into this shop and ask how much it would be to diagnose and replace the thermostat and water pump - they quoted $57 for the diagnosis and $657 for the work. When my husband dropped the car off they wrote the quote much higher so I called to dispute it and was told this was there standard price. I asked them not to work on the car because I didn't feel comfortable with the sudden price change. When we picked up the car it had been moved and I asked why they said they were about to begin the work when I cancelled. I drove it across the street for a diagnosis at another shop and was told that the Coolant hoses were disconnected and all of the coolant was running out of the car...and the car could not be driven it had to be towed!!! Costing us even more money!!! There were no leaks when the car was dropped off at CME. The thermostat light had come on a few weeks earlier we filled up the coolant, nothing was leaking because the car sat in our drive way for two weeks while we were on vacation....until we could drop it off at the shop. Please beware of these vindictive crooks...

Came in for regular service. In and out the same day.

Do not go here! The Tech and the Boss were very rude to say the least. They charged my twice for a job they screwed up the first time. Then after three hours of telling them I wouldn't pay them again to fix their mistake, I was PYSICALLY and verbally ATTACKED by the tech. I don't care how much you disagree with someone, it is not okay to PULL YOUR COSTUMER OUT OF A MOVING VEHICLE!

Both times I've visited Antioch Tire and Auto Center they have given me great service. The people that work there are friendly, knowledgable, and who can complain about getting almost half off on changing your transmission fluids? I will definitely be a returning customer!

Knowledgeable and very Professional. Arrived on time and finished job in expedient manner. So satisfied, that I'm already setting date for Dan to start another job on second car.
