It's too bad not many people have posted their smog results as we can learn from the HUGE differences between them (as shown with just 3 results above).

Anyway, California is pretty lenient when it comes to vehicle inspections (compared to places I've lived in the past).

Here's the California pseudo-3-part inspection procedure described.

FYI, where I live, the bay area, is an "enhanced smog" area so our cars are driven on a dynamometer while being tested.
