You guys should be a good judge of value for a 93 typhoon?I have a 93 black/black typhoon with 15k miles and completely stock.I bought the truck new and the only non stock item is a dealer installed electric sunroof that was installed before I bought it.I have been dealing with someone on a trade for a low mile buick gn and would like your input as to the value.It has been stored for all its life in a heated garageand has never been waxed yet.Also has never been dirty just dusty Thanks
