What is the correct price when you're talking about a car so rare you'll never see another in as good condition? Or maybe never see another at all?
35K is a lot of money, but if that make/model is what you're looking for, you aren't going to have a lot of opportunities to buy one. Maybe that isn't too bad of a starting point.
PS....looks like maybe a late '50's Desoto or Chrysler in front of it.
