I found out about this movie in a book about VW bugs that I picked up at a used bookstore having recently started to drive a new beetle (the book came out at about the time of NBs introduction so it's in there). The book whatever it was called, was really delightful. This movie is a very retro style documentary with a lot of annoying "documentary" hick music used ironically/humorously I mean stylistically this was not a movie after my own heart, but basically the filmmaker showed off these peoples' art cars very well and gave them each a bit of time to say what they're about (the cars and the people) and... the result is by no means without lots of surprises and a sort of strange mixture of happy/sad throughout...
highly highly highly highly I do say do see it....
