hot rodder
Someone who's really into classic cars. Usually the cars are that of the American market, built for speed, used in showcases, and in most cases are extremely rare, and/or have been discontinued.
"Dude, why does Joe have all of those old cars? I mean they're nice and clean but... old and obsolete!"
"That's what Joe does, man. He's really into that kind of thing. He's a hot rodder."
