The rates here at Auto Diagnosis are pretty competitive. It is a small repair shop and needs to draw in new customers with lower rates. I brought my car in for a routine smog check. There was practically no wait for them to take my car in since it was a slow weekday. But, after they took it in I still had to wait about 3 hours. Luckily, there was a little shopping plaza nearby to distract me for a few hours. The workers at Auto Diagnosis just pretty much did their job, I did not notice anything spectacular to rave about or anything bad to complain about. Go for the low rates, I say.
