 Bought new. Paid cash. 10K miles in less than a year. Mileage average 29.1.  Quiet, comfortable, great tech. One caveat. Get instruction from your dealer's techie. I'm fairly savvy about such things, and figured out much of it. Consult with dealer's techie revealed things I hadn't discovered on my own. The owner's manual reads like a tome on German theology, and as a seminary grad I should know. The clicking sound you hear when first starting off is the turn-on of the ABS. Well into year 2 and Doody the Audi is still the car I thought it would be. MPG still around 29 and still very quiet.
