I have lived in Manteca for 30 years. I trust their advice, and recommendations. They have worked on my Chevys (Silverado and Astro Van) and now my Toyotas (Tacoma and Sienna).  You will be guaranteed high quality customer service, thorough explanations, and HONESTY.  I was impressed when (after 6 hours of labor), they could not replicate my AC (Silverado) problem.  Their charge = FREE!  If you are buying a car take it here for inspection as well.  Any negative reviews on this company, I look at suspiciously. - Vincent D (5 star review found on Yelp)
