for those knocking on the 240's stock performance, the '64 mustang wasn't exactly a performance icon either.
bottom line, what determines whether or not something becomes a collectable is the willingness of people to plop down good sums of money to buy them. and that urge is generally driven by nostalgia. 30 years from now, you'll be think back to when you had a fun, light weight fast rwd car that was easy to work on and want to enjoy that experience again. Sure the FD's and supras will be at the top of the pile price-wise, but there are so few of those that people will snap up 240's when they can't afford the FD they always wanted.
