Sorry about passing the 10 year limit, but time does seems to fly by
At least the Saleen S7 still qualifies and some of the '99 S351 cars.
Saleen made some low number cars like the "Extreme", Parnelli Jones and Dan Gurney models with the last Mustang body style change. Now that Steve's no longer involved with "Saleen", but with his own SMS company....I'm not sure what impact this will have on the collectibility of the newer models.
