I know this is way off topic,and should probably have its own thread....but..(there's always a but)
No one would have guessed that way back when, certain cars would attain huge value in years to come. I've an old 'Mororsport' magazine from the late 50's. Its got a great ad in it where a punter wants to SWAP his 30's Bentley for a Ford Pop.....
My day job is supplying parts for Fiats and Alfas (modern). I supply genuine, aftermarket and used parts. Take a twin spark engine (used) from a modern Alfa. I can get more money if its for a 147 than a 156, and I can buy 156's for next to nothing, where 147's still have a decent value.I imagine the same would hold true for modern Lancias, as in a Thema engine is not worth that much for a Thema, but you could expect more for it, to an integrale customer. I know its not exactly the same engine, but is still worth more for the Delta application.
Exactly the same thing happened the Aurelia, Sedans were not as popular as Coupes, and which one attained the higher value later on.
I'm kind of beginning to appreciate the value of certain modern spare parts, V6 Alfa engines, chain driven Alfa Nord engines etc. That Thema block David mentioned was well past its sell by date (leg out of bed).
