The manager was pleasant enough. However, I brought in my 2012 Ford F150 with 69000 miles for a smog check and presented my Groupon voucher. The first thing he did was charge me an additional $20.00 and said this was a discounted price. Then he pointed out that the voucher was for STAR only vehicles. I have no idea what a STAR only vehicle and neither did he. Then he added the $8.50 for the certificate. The technician stated my vehicle failed the test. Upon an immediate retest, it passed. The manager proceeded to charge me another $20.00 for the retest. SHADY!!!! I do not recommend this place at at all.

Technician was nice and friendly. Smog was done pretty quickly. Read fine line before purchasing Groupon or else you will have to pay extra in addition to certificate.

Disappointing that hours posted on Google had them listed as opening at 8am but I waited until 9:30am for anyone to show up. And of course come the additional $10 for STAR certification and the $8.95 certificate fee. But then again it passed, so can't be completely displeased.
