Yeah I think an out of state purchase would work, following your guidelines of history of the car, etc. I also think that 'loop hole' may be closed in the future. I would guess a 1965 titled car would still have to be 'smogged' once a year? Which shouldn't be a problem as the requirements are pretty lax for 1965.
PS My car is no longer for sale.
A guy offered me a fair price AFTER I pulled my Ad, and when it hit me I could really actually loose the car, it scared the crap out of me. No sale!
