Putting my '03 Gt up for sale to purchase a newer 5.0. It is a red manual trans with black leather interior. Excellent condition and only has 37,500 miles. Never seen winter and barely in the rain. Only a few mods: Flowmaster cat back, 75mm throttle body with JLT CAI, tinted windows, Mach 1 grille delete and chin spoiler. Paint & interior are about 9 out of 10. Was going to ask $9000 to start. Never beat on - well mainained. What do you think it is worth?
