Had my smog check there twice and both times it was fast and efficient. They do have unpredictable hours, hence it's best to call ahead and make sure they are open. Also, start by saying you have a coupon (screenshot), and they will honor the online coupon price.

Came here to get a smog and it was super fast even with one car already there getting tested. Don't forget to show the coupon from their website.
Note: it used to be in the 76, but the gas station is now Chevron.

Got a smog test done in 10 minutes. It cost $85 for my 2025 Lexus
