Possibly just as a hobby but all the same he told a villain who destroyed a car in his backyard that he was going to fix it, eventually, and he also apparently regularly attends auto shows and competitions (then again he enjoys all forms of competition generally) since Tiny, Goat and co. know Coop well as a contestant and salvager.
So it's like that show Car Warriors, except with absolutely no other contests or business or schedule.
