Matt, if you obviouslyhave access to a computer, use this handy little trick that I use to get all the photos of cars that I need--enter in "1957 Chevy for sale" into your google search engine...
Voila! You;l get literally hundreds, maybe even thousands of sites and photos of cars, with their sellers eager to show off the whole interiors, exteriors, with details about the cars often listed too. It's a guaranteed winner!
