Getting a used 2014 Audi A6 2.0 having done 75K kms for a rather good deal. What should be my concerns as a first time Audi owner?

As it is my first time buying a premium sedan, I am nervous about the running costs. My job is such that I would be doing about a 100kms a day. via /r/cars http://ift.tt/2tFndP6
