I'm doing some research on this B-movie from 1957. I would like to know the makes of the two convertibles at the beginning of the film.

The good news is the film is online (for free)... http://www.fancast.com/movies/5-Steps-to-Danger/147676/857000017/Five-Steps-To-Danger:-Full-Length/videos?cmpid=FCST_share&skipTo=0

If anyone could help it would be greatly appreciated (it's actually a pretty decent little film too.) I also believe it's airing on TCM in August.
