Been going to this shop for years, but they're different now. Brought in a car for smog with all emssion systems passing, was failed for a small leak past the catalytic converter, this means there was no harmful fumes, just a little bit more sound. They also left the keys in rhe ignition which reset all emissions…

Been going to this shop for years, but they're different now. Brought in a car for smog with all emssion systems passing, was failed for a small leak past the catalytic converter, this means there was no harmful fumes, just a little bit more sound. They also left the keys in rhe ignition which reset all emissions monitors, meaning you can't smog it again until you do a very complex drive cycle again. Never coming back. They already knew they were gonna fail you, and still screwed you over.

Another bonus is that they offer refurbished batteries, which is a great, more affordable option if you need a replacement. It’s nice to see a shop that goes the extra mile to provide helpful services beyond just the smog check.
Highly recommend this place if you’re looking for efficient service and knowledgeable people!
