I didn't read through everything everyone else has said, but I purchased a used 17 RS7 roughly 2 years ago. Mine had 2 previous owners and 50K miles. I was kind of picky when it came to the packages I wanted mine to have, so I think I looked at nearly every single 17 RS7 for sale across the country at the time.
Some things I had to do in the first year that you should be aware of:
Brakes! My rotors had been pad slapped over and over again from the previous owner(s). Luckily I found another forum member selling brand new rotors (AUDI OEM front and back, non-carbon package) so I grabbed them up immediately. With new pads from Power Stop, I'm good to go for quite a while and since I was able to get a deal on the rotors here on the forums, total cost everything was less than $1,400.
Water pump. Mine started leaking about 5 months after I bought it. I'm sure the previous owner knew it was on its way out. Luckily, I had a warranty from where I bought it, and everything was covered under that. They also swapped out the thermostat housing which has a small crack in it.
Turbo oil screens. This should go without saying, but you need to address the turbo oil screens at some point. Mine are getting replaced under the recall at the end of this month.
There have been some minor suspension issues that have been dealt with, mostly normal wear and tear. Nothing crazy at all.
Apple Carplay came with mine.
I opted out of the comfort seating package in my search. I wanted those beautiful diamond stitched seats.
I've went through the gambit of tuning too. Tried APR and VPS, ended up going stage II with VPS ECU and TCU. Loving the hell out of it so far.
Oh, almost forgot, I added front and rear camera's too, thanks to a 3D printed mount for the rear window (looks OEM).
My next adventure is getting remote start going without sacrificing a key.
