One reason could be the exploding stock market. Investors are moving more money there and away from collector cars. It was the same 10+ yrs ago when Hemi cars and Boss 9s went from $500k down to $150/200k. Now you have new bidders that have made money on Wall St and are looking for investments, but at a cheaper price point. People will still pay for 1 of 1s, but modern cars are artificially shorted. Look at how old sports cards are still valuable and the newer artificially short printed cards have become worthless. Just my long winded .02 cents... lol
