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.

Like some of the other reviews mentioned, the service was pretty fast. On the phone he said there was only a short wait. Maybe due to location, a smaller street off main street Magnolia, so there was only one person ahead of me and one person after me. I got there 3:08 pm Wednesday and finished the smog check at 3:25 pm so really about 15 minutes! I liked the two open seating areas, could walk through to front waiting room or stay by car in back seating area. I paid cash and he even confirmed over the phone that it was ok that I misplaced my car registration paper (he could send the pass results electronically). Yay! Thank you, I already told family about this hidden great customer service and low-cost place! (I also liked that it was smog test only so I don't have to worry about them trying to upsell me on something wrong with my car.)

Every other smog test locations would have charged me regardless that it was incomplete, but Diego showed me the results are incomplete and suggested I drive more. He didn't charge me, so I had the option to come back or go elsewhere. I run my own auto repair and off-road performance repair for decades and stand strong with being honest. It goes a long way. What he said wasn't completed is exact, I confirmed it, drove the drive cycle needed and came back for a successful smog test. My experience is with Diego and I absolutely will bring my business to him. We need honest business owners like him.
