There are strict laws governing out-of-state vehicles from entering California. I bought a brand new 2009 Grand Cherokee SRT in Arizona and I was required to get a certificate of inspection and smog check - this is on a new vehicle that carries a 50 state compliance label from Chrysler.
On top of that, you have less than 15 to 20 days to make it all happen or there are hefty fines.
I suggest becoming an Auto Club member and processing through them - they can guide you through this process better than the California DMV where we employee the mentally challenged.
If you do pursue this, make sure you have all your facts straight...
