what's the blue book value for a 1985 Toyota supra

Go to Nada.com or Kelly blue book.

Really, anything over 10 years old doesn't have an accurate "book value". It boils down to condition, and more importantly, how much someone is willing to pay for it.

That is a cool old car and it is worth some bucks especially if it is not wrecked or rusted and runs good- forget the blue book and go for the big bucks-

I can get one for $2500 It’s window trim, other little things, interior needs to be clean, I just need the original wheels
