How much is this car worth?

[89firebirdws6]

I bought a 1989 Firebird Formula with the WS6 package and Borg Warner 5 speed with 9 bolt rear. It also has 67k original miles on the TPI engine. I paid 3500 for it. The interior and everything else is near perfect and original. But the original paint is oxidized and the clearcoat is peeling in some spots. I'd like to get a new paint job to the original color.
