They will disappear from lack of repair parts long before they disappear from any political intervention. Or, from shortage of fuel at reasonable cost. The old ones really didn't get that great of MPG. Today you can get turbo gasoline vehicles that get 35mpg and make 300+ hp.....

And while the old cars may not have computers to break, plenty of other stuff did, like climate control, relays, wiper motor mechanisms, and RUST.

I almost never see MB's around here earlier than W203/W210/W140/W124. Very rarely I see a W123 or W126. Plenty of R107's though.
