The "collectability" of a car is determined by the "want" for that car. '70 Chevelle SS 454's are collectable because people want them. I don't see the 94 & 95 Mustangs reaching a level like the Chevelle's, but to the niche market who likes them they could be very collectable. A "tastful" selection of mods., exhaust, intake manifolds, some suspension etc., could add to the collectable nature. It's all about finding the right ass for the seat.
