Emissions testing service near Vacaville, CA

Great place. Doesn't gouge or try and take advantage of folks. Great mechanics. Shamin Miller

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.

They went out of their way to accommodate my needs. They explained every thing to me, and even took my motorhome to finish the smog testing.

Tim is the Most Amazing Mechanic I’ve seen in my 40 Years in the Car Business ! With 3 ways to fix the blend door ! He choose the one for the customer’s best pricing ! The dealer low balled Me & He took a 8 hour job to four hours . The factory set the HVAC actuators to the wrong pressure ! Tim re-set the actuators In The Body Control Module (BCM) after he was done . We now have heater & A/C back again .Tim is a Get Her Done kinda GREAT mechanic! Thank you so much ! After 40 years in the car/truck business He is the go to Guy of Auto Repair . ??????
