Emissions testing service near Napa, CA

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

I’m always happy after getting my car serviced at Precision Motor Werks! The turnaround is quick and prices are fair. I don’t have any complaints, even after 4 years! Brian is an excellent mechanic and I trust him with my Mini.

Dave is a great mechanic who does a great job! We have him work on all of our cars. He is a very kind honest man I trust him and this is very important to me. I highly recommend Empire Sport West. They are the BEST! Linda D. Santa Rosa CA

I have been going to Richard at European Sales and Service for over 6 years! The service I have received has been above and beyond of what I would expect. I am impressed these days to find great customer service, fair prices and honest people. This is the first review I have ever taken the time to post! Thanks for being the best at what you do!!

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 . ??????

Founded in 1977 by owner Bob Weitz within the city of Napa. At the end of 2011 we moved to our new facility off North Kelly Road in Napa. Our new 15000 square foot shop located right off highways 12 and 29. Just a few miles west of the Coredlia truck scales. We pride ourselves with being one of the cleanest facilities in our industry today. We offer mobile road service for commercial vehicles in Napa and surrounding counties.

I had a long time mechanic who passed away. I was referred to Williams Auto Care and will be a long time customer. They are fantastic. Fair in pricing, detailed in their work and customer oriented!. They identified future work, but did not proceed with the work!! I appreciate that. They will get all my business.
