Free bump for a great mustang. If you end up trading it in please let me know what the dealer offers you. I have a supercharged very low mile 05 im selling and may have to go the same route as you.
Wow. The local dealership about a year ago offered me $10k for a worked over and supercharged 05 GT with 13k miles. $18k is a pretty good deal especially if you are trading it in for something new so you wont have to pay the tax on that portion (at least in NY you dont). Good luck either way!
