One image was already uploaded for Beavis and Butt-head.

I promised I would get more, but ImageShack didn't promise me they were going to let me add more than one relevant image per upload. So I'm going to have to load them up directly in the forum. Here's at least one image of the Ford Aerostar from the episode "Patsies."
