With TV such as the staged "American Pickers," "Pawn Stars," etc. and faster computers, the days of finding a score at a garage sale, barn, etc. are coming to an end. EVERYONE is getting on the net to see what they have and pricing accordingly (if not higher). Either way, prices for rare C&V models such as the Paramount, Krates, etc., are going to escalate. As supply wanes, well, we know the effect on prices.
Additionally, while it used to be commonplace to see kids playing baseball during the summer in just about every neighborhood in America, it's no longer the case. iPhones, XBoxes and the like have taken their place with one notable exception. Kids cant drive until they're 16 (at least the majority of them can't do it legally). They still ride bikes. When the time comes that they'll be able to cobble up a few bucks, they'll pony up for a classic to add to their stable just as we've all done. I'm not exactly sure what tomorrow's "classic" is but the market will roll with the changes.
