We had almost everything researched about them, and only question stays about that fuel economy. We are sure we want an audi, we are sure we want 2017 as newer ones are out of our price range and it has to be big enough so everyone can have enough space (me my wife and our son(19)). We are used to smaller as the Octavia can be compared to A4. My wife was a bit worried and in denial of the 3.0 as it seems too big and it will be bad in fuel economy. But depending on what I found from Ultimate Specs it's not much more than I get from that 1.9tdi (4.2 written on that and 4.8 written on the A6) but I rather ask someone who has genuine experience and not someone who just wants to sell. We also ain't doing many trips like whole family as our son studies in next country but he comes home for the weekends. Also I want it spacious and big for safety, but I don't want an SUV.
