Great service, reasonable pricing and good communication. I originally went to Dublin Chevrolet to have my Tahoe looked at. This cost me $160 just to get my car diagnosed and a quote to fix the air conditioner for close to $700. The communication was so poor by the 'service rep' I asked for a manager who gave me the same runaround. Complete waste of time and money. I called Tri-Valley and spoke with Don. He got me in the next day, took care of my air conditioner, oil change, 30-point inspection, changed the air filter, all for a third of the cost. And he called me like he said he would. I'll never go to Dublin Chevrolet for service again, not when I can go to Tri-Valley Automotive. Seriously, a no brainer.
