Hi Sean,

Without knowing the year, we can only give you rough ideas. If it’s a pre-2010 model, it’s the A6 that is now two generations old and so will only be worth around €6,000 with that sort of mileage on it. If it’s a 2011-on car, it’s the previous generation car and so will be worth something like €11,000 if it’s around 2011, rising to €17,000 for 2015 and later cars.
