I made an appointment for a smog test online with a $30 off coupon (go to their website and click specials). I got a confirmation email for my appointment request within 24 hours and a specific appointment time within 48 hours. On the day of my appointment, I arrived on time, and they took my car right away. They said it would be about 30 minutes, so I decided to wait. They finished my car in 15-20 minutes, and the smog test plus the certificate was $36. The staff was very kind and courteous, and they even gave me a free air freshener for my business.
