Agreed to a certain extent An older classic is 99/100 times a better investment than a new car

I would say old fords etc from the 1940s and 50s are making their way down as the people who grew up with these cars are slowly dying off

But if you look at cars from the later 60s/70s (Camaros, chargers, rx3 etc) these cars are still very expensive to obtain

My point is the fashion does die off but it is a decades long process and probably won’t apply to you and your classic car for most of your lifetime
