Interesting... no one has listed a limo or a van yet. And when I say "van" I'm talking about the very popular (back then) custom full-sized vans with the fold-away bed, carpet on the floor, walls and ceiling, stereo.... Behshad's entry is almost a van but.....
Quick side story:
Many years ago my wife and I drove up to Lake Geneva, WI from Chicago for the weekend. Awesome little town and super fun too! Anyway, when we were checking in at the hotel, we noticed lots of teenagers milling about and asked the guy at the desk what was going on. He told us the hotel was hosting the prom for some nearby school that evening. We must have looked disappointed by his answer because he immediately told us not to worry about the noise. The prom was for a school for the deaf!!

True story.
