1979 Chevrolet SWB cargo van. My father bought it and got it running back in the mid-1990s, when I was about 10, and I drove it for the first time around then, too.

It was bronze with tan interior and orange carpet, and at some point had been used (I suspect) as a mobile whore-house. There were red lights strung up in the interior, and the bad was customized with a king-sized bad (with a very suspiciously stained mattress).
