- $29 for one smog check ($70 value)
Primos Smog has been conducting smog tests on vehicles for nearly 40 years. The facility is test-only, meaning it does not perform any repairs or adjustments. That's good news for drivers, since it means that any outside repairs recommended by the team are absolutely necessary and not an attempt to make a few extra bucks. What's more, Primos Smog offers free re-testing for cars that fail or accidentally sleep through their first exam, and the crew will send all passed certificates directly to the DMV upon completion.
