I took my car in with my check engine light on, knowing that it might cause a snag in passing the smog test. Bob could have easily taken my money and told me the car failed. Instead, he explained that he could test it, but that I would be better off having it checked out before he did. So I got the work done and went back. I was in and out in 10 minutes. Quick, convenient, and Bob's a good guy that appreciates your business. If you need a smog test, this is the place to go.
