Hi, I am searching for my first Audi A4 and so far narrowed it down to two versions. I have a few questions if anyone can shed any light. 2016/17 A4 S line 3.0 TDI Quattro 218 bh with under 20k on the clock vs 2017 A4 S line 2.0 TDI 190 bh under 20k are the two of interest. Any input would be great. Main questions: What are the differences between the two in regards to MPG (Mainy urban driving on a daily basis.) I suspect the 3.0 may drink a little more but checking online only a one or two MPG or so more than the 2.0 . What do these cars truly do on MPG ? Is there a way to verify the mileage ? I would prefer to buy from Audi via the used approved. But haggling seems to have died out in the UK from last time I bought a car. Are there any pro's and con's that are of concern between the two. Is there anything else that should be considered. Any advice would be much appreciated and thank you in advance.
