Hi guys,I found a local ad on an 84 grand national t-top car..I don't know much about the hot-air cars..the car looks to be all there,the he owner says it is a true g.n and completely stock besides new upgraded injectors..car is solid and looks to ready for paint..I own my own custom bodyshop,and was thinking his could be and nice one to add to my collection.whats it worth,and what should I look for.im going to go look and it tomorrow morning.
