DougR,
Just to clarify your understanding of the SB-100 bill in California it is for newly built cars only. BUT, later they added SB-1578 which uses the same 500 numbers so that people who bought cars out of state could register them legally in this republic. That is why you got a number with a turn key car. As long as you buy it from a private party and don't have it built by some manufacturer, then you can use the SB-1578. I just wish they had used another 500 numbers instead of lumping it in with the 500 that SB-100 users are trying to get. Also the law there seems to have one thing that is better than SB-100. Here if yo apply and the 500 numbers are used up already, then you have to have the car smogged via the date the engine was manufactured instead of just waiting another year. So anyone trying to get a number make sure they don't start the process if the 500 are already gone, because they won't reverse it and let you wait until next year. And the California DMV is as screwed up as any in the world. No two seem to work the same way.
