It seems to me Model As have been relatively stable in price for a long time - a good supply and decent demand at market prices. I do think the market is pretty slow on prewar non Fords (Fords in good bodystyles still have a following - at the correct price, A, T, V-8) but sound for Fords, brass cars and most Full Classics.
Tough to say why certain cars take off as 700rpm points out. Not to criticize a VW bus, they are cool, but $50K? Insane, IMHO but the market disagrees. Same thing with air cooled Porsches and 190 SL MB. The 190 SL is a real mystery to me - nice enough to look at but under powered and ignored by MB enthusiasts forever - now more expensive than an XKE??! Strangely, I am a big German car fan but happened to rattle these three off. Maybe because I follow that market more.
I guess a slow market is all the more reason to worry less about nicks and such and drive more!
