Nice to see that 1987 Astroroof on the stage, and I thought that was a good price for it, too.
I didn't agree with the announcer's "one of the few collectible American cars from the 80s comment though"...
I think that category should include the IROC-Z, the GTA, the Turbo TA, the Corvette ZR1, the Grand Prix Aero Coupe, the Olds 442, the Monte Carlo SS, along with the SVO Mustang.
All (maybe except for the Vette) can be bought for reasonable money, and I think all will increase in value in the future.
Anybody have any others to add to the above list?
