Quick and honest little smog shop, it's past the car washing area in the back. I was a little…read moreconfused at first. But they were fast and decently priced. Cheaper than most, considering I wasn't trying to drive 17min for 38$ I paid 58$ for the convenience since it was in my way home and I had other errands to run. Update: the other errands to run were an oil change but connected to this place next door they do oil changes. Synthetic blend was their cheapest they don't do regular, but it was the same price as Lenny dykstras and saved me the trip. Although it didn't come with a free car wash like Lenny's, still very convenient.

This place raised some serious red flags for me. I was the third person in line whose car didn't…read morepass, and the two cars ahead of me were also told they failed their smog tests. Seeing three vehicles in a row fail makes you start questioning what's really going on. I understand CARB regulations can be strict, but the process here feels questionable. You still have to pay the full test fee, then come back and pay again (or pay a reduced retest fee) after supposedly fixing the issue. When multiple customers are being told they failed back-to-back, it starts to feel less like coincidence and more like a pattern. I'm not saying every failure is wrong, but based on my experience and what I saw with the other customers ahead of me, I'd strongly recommend getting a second opinion before spending your money here.
