Hows the reliability on a 2012 Audi A6?

Thinking of buying an Audi A6. It's a 2012 Prestige with 86k miles on it, and it has the 3.0t motor. Pulled the carfax and it looks like it has been serviced regularly, at an actual Audi dealership. I don't know too much about German cars, so I wanted to check if anyone has experience with this specific model. via /r/cars http://ift.tt/2trqSNM
