i have an all 100 % oringinal 87 t-top 5.0 mustang with low miles and is the same as it was when it rolled off the show room floor AND am the original owner. in everyones opinion, what am i looking at for what my baby is worth? its sat in a garage for 20 + years and im kinda curious now. i had someone recent tell me i could get over $20,000 for it but im not really sure about that, but then again i dont know. anyone have any opinions?
