[urq] Car Hibernation? Audi but non-urq content

[urquattro at comcast.net]

I've recently purchased a "future project" early A8 which I won't have the time or money to do much with for another 6 months or so. It's stored inside and I've been maintaining the battery, but I don't want to pay insurance for now if I can avoid it, so I'm wondering how long it can just sit undriven without risk of drying out engine and tranny seals too much, un-lubing engine internals, distorting tires, etc. 

My urq sat for about 7 months last year and seemed to do okay except that the tires seemed out of balance when I finally started driving it again. It smoothed out a little but they still feel like they need to be rebalanced. I figure you "car stored for the winter" east-coast types might have some good BTDT on this kind of stuff...

Thanks as always for the great input!
