Got car smogged in less than 15 minutes, customer service was excellent, very pleased with Miller Oil Company.

I've been using Yotaluma for YEARS and can't say enough good things about Ryan. We recently moved from the area (a two hour drive) and I STILL bring my Toyota Matrix back to Yotaluma. Honest, fast, responsive. Yes, as good as it gets. Larry F. El Dorado Hills, CA

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.

What a great shop! Prices are really good and service is 5 star!

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.

Great team and excellent service at R&I. Rey has has been our family's mechanic for years and I wouldn't go anywhere else. Gabe Overbay
