well first of all. get a figure on your mustang if you are trading it in. (I sell cars in Atlanta Ga). so to be honest the color you picked on your pony in not a very popular color take in to account any accidents, milage anything more than 10k ayear and it will get a hit. realistic i would say your car is worth 10k to maybe 13k depending on options. with deducting those mentioned above. If your car is paid for that is a good thing. Smart, Brunette in an Mag Grey Met. HOT!!!!!! Good luck on your pic and you can get a new G8 GT for 28k out the door that is what I paid for mine and countless others also.
