I just got in a book on this subject, thanks to a recommendation from a forumite:
"GM in Miniature". It told me a few model cars I would have liked access to were sold
in very low numbers, 50-100, and priced as much or more than $300! I don't understand why there are $20.00 models in very good detail in much larger scales,
1/32, 1/25, and larger, and an approximate O scale (since they are made for model
auto collectors, who outnumber us greatly, forget about getting away from 1/43)
model is ten times the price. I have seen some unusual autos modeled in these large scales, that I would have loved to plunk down on one of my streets, such as a 1930 Peerless sedan. Somebody needs to crowd fund a company to produce
some affordable American models. Rextoys were made in France and sold for $30,
not dime store, but not $300. Brooklin prices keep inching up. Ten Brooklin vehicles
on your layout will buy you a 3rd Rail steam loco. This subject keeps coming up, so
that, at least, means there is a lot of concern about it. Maybe squeaky wheels will get
some grease?
