wagen number stats - N.A. vs. Europa

[alex v. 928s]

I might be finding myself in a position moving to Europe soon. I also 
have to make a quick decision on getting another car for the interim 
period. I've looked at an A6 wagen that I'm interested here in Toronto 
but if I leave for European work permanently, I don't want to invest in 
such a car now.

Question is: Are there more or less Audi wagens on the European side 
than USA? Are the used Audis valued (cost) higher there to purchase?
 Are the export/sales numbers listed anywhere?
