2013 Audi A6 2.0T Premium quattro 4dr Sedan AWD (2.0L 4cyl Turbo 8A)
We have driven entry level luxury cars for years (Infiniti G, Acura TL, BMW 335).
We looked at these again recently when trading in our 335xi coupe - nothing special or exciting.
The new BMW was downright expensive with any nice options.
We looked at the Audi A4, A5, A6.
The A6 has everything - great price, great economy, great interior, and the dealership was much better than our Seinfeldesque BMW dealer. We had to get the A6 and have not regretted it.
