Entertainment..........................

From the movies I've seen, you can drive around in the sand in it.  Other vehicles would just get stuck.

Answer 3

This is not a Books and Authors question.  Somewhere on Yahoo Answers  is a category  about motor vehicles 

A Dune Buggy was, in the 1960s and 70s an open all terrain vehicle similar to a Jeep. You can "Google" it.
