5 /5 K Rick: The shop and the manager have integrity. I was referred to them by my mechanic and have never used their services. And there was a bit of a miscommunication between the man who worked the counter and myself. In my previous experiences with shops, they shrug and put the burden on you as the customer. But at Certified Automotive Repair in Grass Valley they are some people that you can really trust and in the end they made sure to take care of me and compensated me. I recommend them as a 34 year resident of Grass Valley who has used many mechanics. Im on my way to pick up my vehicle from there now.
