Audi has managed to certainly confuse its buyers by introducing a plethora of options and customisations on the car, but still we recommend between buying the 2.0 Premium plus and the 3.0 Prestige. What to choose between these 2 will certainly depend on your need and choice of engine and the performance you desire.
