One of the attendants got me started on the paperwork almost immediately. By 10:55am, my car was already being inspected, and by 11:05am, everything was done. The total, including the state paperwork, was $58--about $15 less than what I paid for my last smog check at another shop. I was really happy with the quick turnaround and the price. Highly recommended! BONUS MATERIAL: - They are a STAR certified station. Smog check was $49.75 (with coupon found on their website) + $8.25 for the CA paperwork.
