I searched and couldn't find a thread .....so, what's it worth?

My old coupe: 1990 Mustang LX 5.0

The bad:
body is decent (7:10?), but subframes were rotted and repaired.
car was in a t-bone (rear) accident, and repaired.
high mileage.

The good:
it's a notch.

I put this bug in my father's ear that he should buy the '86 Mustang I have for sale. But he would have to get rid of my old '90 first (despite have acres of property, mother won't let him have more than one toy). He might have a local buyer, but he doesn't know what kind of price he should ask for.
