Can someone enlight(en?) me on the emission/smog test:

Let's say you have a 78 westy, carburated or injection, do you have to pass
a smog test? is it a 25 years old car/van max law? what about collection
vehicle? (special promenade plate = no smog test?)

I sais Clifornia but any other state for that matter!

Of what i know, California is more strict then other state?

We have a local debate here...
