 Trustindex verifies that the original source of the review is Google. I had a great experience here. I didn’t make an appointment and only had to wait about 20 mins. The actual test only took about ten minutes and the tech was extremely nice. Would absolutely recommend!

 Trustindex verifies that the original source of the review is Google. 做为华人，最怕的就是被骗，因为华人是在被骗中长大的，对于这家检测站，说句公道话，是按照宣传上收费的，我的车十七年了，需要STAR认证，加了十块，共47元，十分钟之内检验通过，本来17点下班，我16点54分到的，也给我检了。

The best price in the area (maybe in the state?), no line or appt needed, and the best hours (open until 6:30pm).

Where I live in Santa Cruz, it’s practically cheaper to buy a new car than get a smog!! (only exaggerating a little)

 Trustindex verifies that the original source of the review is Google. The place has unclear signage so I was confused which door I needed to use. Good news was the wait wasn’t too long for a STAR smog. Mario was helpful and friendly but the overall cost was $78 compared to $45 down the street with Andy’s Smog check 2 years ago. However, the cost of inflation may have contributed to the price increase :(
