How much should i sell my 1989 fox mustang for?
Do you have any pictures of the car? It's pretty hard to appraise a car from a description and a big list of parts.
My guesstimate for the car's value is $7,500-$9,500 depending some determinant factors. The car isn't supercharged, but it sounds like a very serious 5.0 motor with A.F.R. heads and every bolt on in the book. You didn't mention the horsepower but people will pay for horsepower. If your 5.0 is putting out 400 horsepower, than that's easily worth a couple more grand to buyers.
