Hmmm. Well, I do think the F10 is more than a cursory cosmetic update to the E60. That said, good on Audi for upping the ante as you say. Haven't seen an 2012 A6 yet. Last time I checked, a couple of weeks ago, they had none in stock. So, even if it's a better car, you can't get one.
Hate it when that happens.
