Was literally here less than ten minutes ago. This business is GOLDEN. I only had an hour to get a smog check (during my lunch break). I was there 15 minutes total--super quick, easy, and no stress. I'll happily be returning every two years from here on out!

It's been over a decade since I needed a smog. Same spot, great service and still the same old G. Thank you.
