I agree with everyone (so, maybe no reason to add my 2 cents?).
I think some people buy cars because they are 'supposed" to become collectable. The problem is that most things that actually do become "collectable" never started out that way. When they do, it typically takes years. I remember in 1969 when we talked that my 63 Corvette would become an item because of the only year with the split window. I think I sold it in 1970 for $1,350.00. Well, 35 YEARS LATER, oops. Maufactured collectables (like Franklin Mint stuff) never does become desireable because there is too much and too many people speculating (collecting state quarters, are we?). I am sure the new Shelby's will be good eventually, again maybe in another 30 years. Even though the GTs 4000 units is a lot, the main advantage the cars have is that there will not be a newer one to outdate it like there will always be a newer Corvette. Even if Ford does another, it is the classic shape that was the hit. The GT-90 and the others just didn't hit the mark.
Some buyers are therefore trying to recapture what happened to the muscle cars. But do you think anyone who bought a new Z-28 in 1969 or bought a Challenger ever thought they would be zillion dollar cars? I sat in a Challenger TA around 1970-71 that I was considering buying, looked at all of the plastic, and said "what a piece of cr*p". Did wind up buying a "normal" 70 Barracuda for a whole $975.00. Remember racing (no, not with the Barracuda) against Roadrunners, Hemi GTXs, Z-28s, Ss-396s, 427 Covettes, and even a 66-67 style SS-427 Chevelle (only 427 one I ever saw). They were just new rocket cars, but just another new car in a sense (the competition was the blown Willys pickup, the 427 55 Chevy, etc). Never ever gave a thought that some of them may become half-million dollar cars (or in the case of the 427 Cobra, better yet). WOW. As we all know, hindsight is perfect.
I think in the short term, when production stops the new cars at the dealers will go up. After all, the dealers are in the business to make a profit. many will take the attitude that it will eventually sell - which it will. I guess, just from the business side, if I had a new one in the dealership I would go ahead and pay for it at the base cost, and then let it sit. So what if it takes a year, you could still probably make 50 percent on your money.
For my crystal ball, it is a little hazey. Obviously, I hope they don't go down a lot in value. But I also don't car. It is the first expensive car I have had in the garage that it doesn't bother me that it just sits (others I was too worried about the depreciation). As someone already said, just that fact it is in the garage puts a smile on my face :biggrin
