I bought my daughter a low mileage A6 1.9TDI Audi almost a year ago. She stays in the Highlands of Scotland and with a new baby required something economical and safe. What a cracker of an engine the 1.9TDI is, the economy is 51mpg the engine is lively and eager to respond when you hit the accelerator. It is a very comfortable car and if I never had the A8 an A6 could have seriously tempted me. I have heard that the newer 2.0 TDI is not as good an engine but as I have never owned one I cant compare
