While I agree with the general consensus on flat to declining values, the A still has wide appeal as an entry-level prewar collector car. While a lot of people tend to buy what they remember, a smaller group "graduates",or become true collectors branching into the eras of interest, not just their youth. About half of the A owners I know well are younger than me (51), and none would remember these cars when new. The issue is that just like the MGB is to brit car fans, the A is not rare and the supply of good cars meets the demand at current pricing. Any further changes in either direction are unlikely to be life changing. But a good car should find a buyer, one needs to understand it is a competitive market. The silver lining to me, is a fairly steady market. Our Fords are generally easier sells than many less popular non Full Classic prewar cars, for all the reasons, simplicity, great parts and support, etc. We all know about. But they will never be rare enough for huge appreciation.
In terms of younger interest, I spent labor day weekend at the limerock historics and it was incredible how many young people were there, some I think will eventually get into prewar cars if not already there...
