Common questions
Will my out-of-state vehicle pass California smog?
Most modern vehicles (2000+) sold anywhere in the US should pass. California's emissions standards are slightly stricter than the federal standards, so pre-2000 cars sold in non-CARB states sometimes fail.
What's a VIN verification?
A confirmation that the VIN on the vehicle matches the title and registration documents. Our shops are CHP-authorized for VIN verification on most vehicle types. Takes ~15 minutes.
How long does the whole process take?
At our shop: smog + VIN + brake/light typically 45 min to 2 hours. The DMV step (with REG 343 + smog cert in hand) is appointment-dependent — usually 1-2 weeks for plates.
