And the research starts anew....you can get a gently used 2012/2013 prestige S4 for that much...

I feel obligated to remind you once you start talking about Audis.

There's a reason Audi resale falls off a cliff when it goes out of warranty. You may say, "But it'll be under warranty." Perhaps, but then that's all time you'd end up wasting having to take it back to the dealership, not to mention the frustration.
