Let's say you've got a 5 pack with a Z06 Vette GM, or any other car. Now, trade wise is that set worth more because you've paid more from the start? I mean, Green for Green, but doesn't sound right?! Couple regular issues tossed in?!

I'd say no - especially since you would still have your 4 regs to sell.
That would be like if you bought a 5 pound bag of garbonzo beans and tried to sell one bean for the price of the whole bag.
But as we say in the car business, "There's an ass for every seat!"

Well that depends on if you sell/trade as a five pack.

ive been tryin to figure that out as well.i have a cruise in five pack with the 69 vette gm.i think im gonna try an get the whole set but i dont know how much each one is worth.johnny
