Maintenance isn't "that" bad, but be aware if you're out of warranty and anything major breaks it will kill your wallet. I have an S4 so it's even pricier than the A models. If you know how to change your own oil, do it; you'll save $75+. As far as scheduled service goes, let Audi take care of it. It's expensive($600-ish), but they're extremely thorough. I have an aftermarket big brake kit and Audi quoted me $725 for new pads and installation. I did it myself for $250 (keep in mind, I have 6 piston calipers w/ 14.5" rotors so it's not cheap).

Fellow S4 owner here. It can be expensive to maintain, but worth every penny.

Anyways, I figure the price he was quoting is average yearly for an out-of-warranty vehicle. I spend about $300 on routine maintenance a year, then every once in a while something actually breaks and it can be expensive. I think when I needed new exhaust it was about $3k. I'd say it averages out to about $1K a year. More if you take into account that I have a seperate pair of winter wheels and tires.

well the cars have a pretty decent aftermarket, so if you needed a new exhaust you could have just gotten an aftermarket one...or bought a used one on the forums for a few hundred
