The prices are going down because of several reasons. First, the speculators and investors that drove the prices up, have moved their money into other areas because the potential for making a quick buck are gone. This is often what happens with a "Fad". The market has been flooded with muscle cars, and there just isn't the same demand. They will now move to cars that have been undervalued, or forgotten, like 40's and 50's cars. They'll start buying them up, cause a frenzy in the market, and sell when they feel they've topped out, just like with muscle cars. Collectors are moving to other areas that are even more rare, like vintage race cars, one offs, etc. People that borrowed money from their home equity are dumping the cars because their home values are falling like a rock. People that were considering cashing in their 401k's or home equity have pulled back and decided not to. Watch gold prices, and you'll see where a lot of the money is going.
