What you were looking at, were some of your basic "Pimpmobiles" or "Jukeboxes" of the early 70s. They were bascially done by after market body and trim shops. The most interesting I think, was the white Eldorado used in the early part of the film, that was used to kill Bonds driver. Its basically a Corvette with Eldorado body panels. These cars mostly are looked at with disdain by many "purists". Myself, I have always liked most of them that were done "right". They incorporated many of the trims of the classic cars of the 30s, and when done "right" was really quite impressive.
