1. So, if I drove my Toyota Sienna more than 12,000 km, do I still need to request compliance letter from manufacture?
2. I'm confused. if i bring cars from Canada, I understand that I need to register them in DMV California in 20 days to avoid penalty, but to get SSN, I have to wait at least 4-6 week. So, even in theory I cannot do it

(same regarding driver license).
Is anyone knows if for first couple of months, I can drive my car with Ontario plates and license (like tourist). And go to DMV after I get SSN???
