As an update, I returned all three of these awful PS-1 cars we bought and replaced them with another 3-pack of Vision PFE reefers. The person to whom I spoke at the dealer said I wasn't alone in my decision, with folks upset over the lack of the fundamental, telltale sound that these "rail sounds" cars should have but don't - the clunk-clunk rail sound trains make as they role down the pike.
CJack - read your post about muscle cars and I'd agree - many folks mistake investments for (a) speculation, and (b) things that depreciate. The OGR mag even had an editorial a while back, comparing toy trains to vintage comic books. While comic book collecting Is speculative, as an advisor to the Overstreet Comic Book Price Guide, I can tell you this is still an apples-oranges comparison. Having said all that, I wish I still had the very clean 340 six-pack R/T 1970 Mopar Challenger I bought in 1989 for $1,800.
