I have followed this post from the beginning, and have watched the rhetoric build. It is a great post because it brings into play personal bias, rarity, supply and demand, documentation, urban myth, missing motor, last of an era vs the era was all ready dead, and on and on, all in one cool WIW. IMHO I say 50K, in today's market, using some of the sound reasoning in some of the previous posts. The criteria used to price rare & obscure cars is totally different(and hard to peg)than that of all other combinations.
