"I called ahead of time to make sure I didn't have to wait with my smog check. Was in and out within 15 minutes! It cost me only $40! While waiting I had a great conversation with Naraj. All smiles and good conversation. I came in for a maintenance check-up of my Toyota Rav. I had concerns about my tire pressure. Got them all inflated because of the cold air makes the pressure in the tires go down. Vu came through again! Coolant fluid was leaking. He ordered the part, and a few hours later, my car was fixed, safe to drive again. And that on a Saturday. Excellent service!" Read More Reviews
