I'm watching a movie on MGM Studios HD movie network on cable television. It seems to be a take off on the slightly more popular "Valley Girl" movie where a group of stereotypical 1980s teen girls valet park cars. Despite the movie's rather poor production values, it contains numerous examples of some real vehicle eye candy. There are plenty of high end 1980s sports & estate cars and some perfectly restored 1950s American convertibles. Here is the imdb entry: http://www.imdb.com/title/tt0094237/

This may be hard to find, I have encountered other movies played on the network that are relatively exclusive. Many have not been released on DVD and finding somebody with the original home video VHS from 30 years ago is unlikely. I haven't checked personally, but maybe it might be available on YouTube or other open source media site. Good luck!
