If that idea is going around here, it must be in the classic car world, because classic car owners cannot handle classics that are still being built.

I have come across this attitude on this side of the pond, but I think it is a small minority, probably because there are so much more young trads here.
I have come across that attitude here in Italy. For many the only Morgan to have is at least 30 years old!
Personally I want a car that has traditional looks and build but with modern mechanicals (modern suspension would be nice too - but you can't have everything). There are days in this part of the world when you are forbidden by law to drive a vehicle that is not at least Euro 2 (emissions)and it is likely to get to be Euro 3 or 4 before long.
I have had classic cars and motorcycles and one is always fiddling with something or searching for spares. I am not saying it is not a worthwhile pursuit to enjoy and keep old vehicles on the road but that I, personally, have arrived at the point where I want something that I can drive and enjoy without getting my hands dirty
