I cannot emphasize how amazing and incredible these guys are. I have been taking my Porsche Panamera and Audi Q5 to them since 2019 and I have never been disappointed. I always enter and leave their place happier than I was when I came and perfectly satisfied with the service. The customer service is exemplary and they also do great quality work at a fair price. I feel like the team there, especially Alex, are my partners and my friends. As a woman I appreciate it so much because prior to using Contra Costa Auto Service, I had become accustomed to being treated much differently and had an overall jaded attitude about auto repairs. I was expecting the worst but was so pleasantly surprised and that has continued over the last 2-years. Both Alex and Dan are amazing, helpful, extremely knowledgeable, competent and they understand how providing such good service is good for business. I HIGHLY recommend them and will refer all of my friends, family and neighbors to them.
