I originally took my vehicle to another shop to have them determine why my car would not pass smog. The cost of the diagnostics was high but since they had a high Yelp rating I felt it was justified. After 2 days at their shop and continually following up with them, they determined I needed a new engine. I knew this was bogus and reached out to a smog expert who then referred me to B & C. I scheduled an appointment with B & C and was able to bring my car in right away. The diagnostics was completed the same day with a recommendation to replace my catalyst converter. Based on B & C's advice, I authorized them to install a new catalyst converter, which was completed the same day and my vehicle passed smog. If I had gone to B & C in the first place I would have saved over half of the cost for the diagnostics and half of the time wasted at the other shop. The B & C personnel were really easy to work with and they kept me informed in real time. B & C is now my new go to place for my vehicles.
