I seem to notice a pattern of people that have owned VW Beetles needing to sleep in them at one point or another....remind me to never buy a bug.   
 
   If you own any car and drive long distances, you will eventually sleep in it, especially if your destinations are fairly wild places.  You are probably dealing with a generation for whom the Beetle was their starter vehicle.  I remember mine with fondness; it was economical, very good on back country roads, and mine would actually float for brief periods when fording streams.
