my friend's dad collected yugos. I always loved em. but collectors are few and only because they are cheap and weird - which arguably might make them more appropriate to the mopediest cars. despite being under appreciated, there was Drowning Mona which featured a lotta yugos quite heavily
but yeah VW air cooled bugs probably still win it. cheap mass produced, bought and forgotten, and air cooled = dead simple to work on, also easily and frequently customizable.
