buying a car out of state
$15k seems like strong money for an early A. (I say this in ignorance, not knowing anything about the car). There is a pretty narrow market for early As.
I believe classic car prices, like housing prices, are over heated. What goes way up too fast comes back down. If you are not in a hurry, I would make an offer and wait it out.
I definitely wouldn’t do a long distance trade. Way too many things to go wrong.
Just an opinion from an old cheapskate….
