Sticker prices are OK here. I've seen a couple good deals on some older model VWs, but never on the Audi stock.
Maintainence is, for a dealer, extremely reasonable. I wouldn't buy a car here because of the pushy staff-- but this is something you deal with wherever you goto buy a car.
I'd recommend Day if you live in the area, or you need work done on a lease vehicle by an authorized dealer.
