“Best Smog station around the area. The owner Francis is fantastic. Price is literally like 40% cheaper compared to other shops that I quoted for. I brought my 99’ Mercedes and he did the job within 20 min and uploaded the Smog proof to DMV right after. Highly recommend this place.”

“I setup an appointment and Francis came on time. Plenty of parking and easy to get-in / get-out. I wish I used the coupon on their page because my car didn't pass the smog test. If I had used the coupon from their page, I would've gotten a free retest. Either way, great place, great service. Star certified. Will repeat.”

“The other reviews read like exaggeration but they are true. There's a reason why it has 5 stars across the board. This is quite objectively head and shoulders above the others honestly. This is literally the only place that has outranked the others on price, speed, efficiency. You won't get any run around, you will get straight pricing only for what's needed, you'll get a set time that gets you in and out faster than other places and I should know having been to all these other places before finding Francis. Once you come here, you'll most likely never need to go elsewhere. Even a further drive is worth it imho. Just try it out once and thank me later. To boot you'll feel good having supported an outstanding individual as a person. I could on with several paragraphs of details but all you need is above. >Most”

“$45 best smog check deal! Francis is super professional, friendly and efficient. Will happily go again next time. Definitely recommend his services. PS:Call to make an appointment first.”
