I have an older car that needed Star Certification. That's pretty scary because you are at the mercy of the Smog Station. It's very easy for them to fail the smog test without an issue, you can fail alone for not passing a visual test. This is how many disreputable smog businesses make easy money - because you just want to get it over with, you'll pay whatever they ask to fix whatever is causing the car to fail smog testing. Not Speedy Auto & Smog. No tricks, they're completely honest and straightforward. If you have any worries in advance, call them and they'll help you know what you need to do to have the car pass. They don't play games. It's family owned, the lowest price I found anywhere and the staff couldn't be more pleasant. For a process that usually is a headache, they take all the worry away. On top of all that, they work fast. I brought a newspaper with me to pass the time, before I finished the first story, they were done. I'm sending all my friends and will return whenever I need a smog certification.
