Drive a '56-'64 Chrysler product with automatic transmission. They might get it started, but they'll probably get stumped when it comes time to shift into gear.
Somewhere about 1974 my Grandmother bought another car & gave my older brother & I her 1962 Fury III 4 door that she & my Grandfather had bought new. We had to get the owner's manual out of the glovebox to figure out how to drive the thing the first time we took it out! :D
