FWIW, several, low mileage verts (less than 20K miles) have sold in the mid teens on fleabay within the last 6 months. from the limited information the OP gave - color options, transmission, coupe/convertible, etc, etc, etc, giving a price here is damn near impossible. $5K seems low, but if it's a 7k mile, neglected POS, that might be about right. a mint, babied, coupe might fetch $12-14K - who knows??? with no photo's, too many variables and a general, lack of information, pricing this thing is just guessing.
this was bad timing on my part, but within the last year, I let a mint, near perfect 90 vert, (white over red, black top, optional hardtop, 6-speed, and 23K miles on the clock) slip thru my fingers. sold for $12.5K -
(to the OP) if that thing is a vert, white over red, black top, automatic, and somebody's baby - PLEASE PM ME!!!
