[s-cars] Winter Storage

[JR]

I'm thinking of putting my S4 away for the winter.  I've never stored a 
car for winter before.  I hear I should wash, wax, check the coolant, 
change the oil, add fuel stabilizer, remove and trickle charge the 
battery (I have a Battery Tender for this), and overfill the tires a bit 
(to avoid flat spots).  Anything else I should know?  Anything specific 
to the URS4?

Some say to start and run a stored car for a while every few weeks or so 
and some say not to at all until winter is over.  Anyone know which of 
these is best?

Thanks,

JR
