I am new here - I currently own an Aud A2 and its been an amazing little car for me over the years. But I think I am going to be applying for an internal job soon, and have always been a fan of the A4 Avant, and I could do with a bigger car going forward and with this new job i'll be getting a car allowance, which basically states that the car has to be less than 10 years old. Ive read in different places that the best engines are the 2.0 TDI Quattro, and the 3.0 TDI Quattro. If anyone could give me there thoughts? I know i'd ideally like to find a car from 2011, with full leather, pan roof, full mmi, s line ideally, but it is the engine I dont know what to opt for. Many Thanks in advance.
