Good luck trying to sell your car in this economy. I had my 03' 350z on craigslist and autotrader for months without a decent offer. I eventually had to trade it in to a dealer for a few grand less than i would've gotten privately.I traded it in for an 04 xterra to take out in bad weather, and so I could keep the miles off the S5. Did you ask audi for a trade in price? Take all the mods out and see what they offer you, it might save you some headaches. Good luck with the new car, it's a lot of fun.
