Sadly unless we experience another bubble (some say QE is a bubble which is probably true) I doubt we will ever get back to the heyday of musclecar prices. Homes in my area have only gone up 4-5% over the last 3 years and this is a very desirable area.
I agree with your opinion but also trying to look at the crystal ball of prosperity and I think if anything and despite the current still foul economic mood that we have a few things going for us long term..
1) Huge increase in oil production which leads me to be bullish on America long term (next 30 years) because it will:
a) Keep a lot of wealth here in the United States instead of sending the petro- dollars overseas to foreign countries that don't like us very much.
b) Effectively subsidize the cost of manufacturing in the U.S because our energy costs are cheap even at 95.00/bbl oil compared to massive manufacturing economies like China because they have to import it.
c) Wages in China and other countries are rising, offsetting this discrepancy that once was even larger than it is now leading more manufacturing to come home?
d) Natural Gas is everywhere here and we are swimming in it. Thereby it lowers manufacturing costs even more.
e) All this created wealth will at some point filter down in the economy into a wealth effect that lifts the economy significantly.
2) We're tired of being broke. People want to spend. They want to live and enjoy and have things. They want to prosper.
3) We're America. If that sounds cliche it really isn't. We keep coming back time and time again precisely because we are America and we all want to be better off so we adapt and evolve and enter eras of prosperity precisely because we adapt and evolve.
I guess I'm too optimistic but the single fact that the world runs on oil, and we will be the worlds largest producer in a few short years leads me to believe that we are entering an era of prosperity even though we can't see it yet.
How this translates to collector cars is I believe that when times are good, highly sought after cars bring a premium and that in a few years we'll be out of most of this quagmire and on a firmer footing nationally and car prices will reflect that.
Maybe I'm wrong but I'm starting to get really bullish on America again.
