Come on here folks -- the moisture IS IN THE AIR (it's called humidity) 
-- little drops of moisture do not just climb up out of the ground, up 
the side walls of the tires, and then onto the car  --  such would defy 
the Law of Gravity, and let me tell you, gravity *always* wins, in the end.

It (the moisture, not the gravity) first evaporates from the ground, 
meaning it is in the air -- if that air happens to be stagnant under 
your car or trapped under your car cover, and has a higher humidity than 
the surrounding ambient air, it would increase the odds that said air's 
moisture may condense where it is.  That's why you want a breathable car 
cover instead of a sheet of plastic, to let the moist air out instead of 
trapping it  next to or under the car.  This same sort of thing is why 
the inside of  partially full fuel tanks gather moisture (and the 
consequent corrosion).

Anywhere there is air, there is moisture, including "dry" garages --  
heated, climate-controlled garages are a different matter, but they 
still have humidity, just controlled and the heat prevents any 
condensation.  This occurs natually in Arid-zona, thus Phoenix Charlie's 
mostly rust free examples survive. 

New Market Opportunity:  car sized Vac & Seal units, to store cars in an 
air free environment -- meaning one would have to first drain *all* the 
gas from the vehilce, as well as coolants (ah, one up for the Corvair, 
but is the Corvair market alone sufficient to support such an 
enterprise?  More impractical would be those inflatable plastic bag car 
covers, inflated with a continous supply of dry nitrogen ...  (I suppose 
you could hook one up to the natural gas line for a dry gas, but seems 
that might be hazzardous -- oh, let's see, this is the crowd that sucks 
gasoline with vacuum cleaners, isn't it -- forget I mentioned it!)
