[Number 3]

Collectable? Absolutely. By the definition alone, it's low volume and no longer available so it will be highly sought after by enthusiasts for years to come.

But if by "collectable" you mean wildly valued I'm not sure sure. Are values holding? From what I see yes. But at sticker? Nope. So anyone who bought low used and has a higher value now? Awesome. But all used cars are higher in value.

Now 30 years from now when we see them at Barrett Jackson, what would they be going for? That, I think, is the nature of the question. In many cases those cars are worth much less than if you had parked the money in the stock market.......unless they are truly low volume e.g. L88 Corvettes.
