I think that's about right. The collector market is driven by guys who worked on cars when they were young. The most valuable ones are are exteremely rare, historically significant and technologically advanced cars, but the majority of the market is cars that everyone wanted when they were in junior high school. I don't think modern cars appeal to those kids in the same way anymore, and the software intensive nature of new cars prevents almost everyone from getting as involved with their cars the way kids did 50 years ago. Once the computer system fails, no one can confidently predict how much it will cost to bring it back. Who would buy a non-running car unless they were confident about who much it would cost to get it running? There may always be a market for Ferraris, but not for mass market cars.
That 1800 is another car that has peaked in the market. If you didn't watch The Saint as a kid, you probably don't really want one.
I'm not sure I buy this. For me it was more the stuff that was out when I was 17-24ish. Obviously unable to afford at that time but still...
and The Saint had nothing to do with it, the guy down the block had one! (I was in my Triumph GT6 so things could have been a lot worse!)
