I have been owning an A4 S line since the last two years.The car is extremely good except
for the central console. It is not as good as an idrive (BMWs console) the engine is perfect and gives 10 km/l mileage in the city and a slightly better mileage in the highway.You can turn off the ESC if necessary. The engine is very silent. The car will have the same feeling in 120Km/h of what u had in 60Km/h or below.
It has an wonderful seating positions, you can also adjust the seat support according to your needs.The Audi has an very light steering which is good for traffic and for indian roads.
