The Avant estate accounts for a large share of the offer and is often the model's best all-round compromise.
Of the 138 used Audi A4 listed right now: 67% are diesel. 64% have automatic transmission. Half are priced under €15,000.
The B8 generation, up to 2015, is now the most affordable and remains an excellent long-distance car.

Consumables cost what premium consumables cost: large tyres, brakes, services.
A high-mileage driver who puts interior finish and long-distance comfort first, with the Avant if volume matters.
