Nice,
There are tons of right up's about checking the cam follower, it can be done in 30-60 minutes depending on how slow you want to be. Mine is crossing the 112K mile mark and has been about the best DD I could imagine.
If you aren't going to mod it, you can probably go 20K+ between follower changes, with aftermarket HPFP they will wear significantly faster.
I would buy it, check the follower / cam yourself and bring it into Audi if necessary. Otherwise, just replace them every 4-5 oil changes and have a great car.
