As mentioned i will hopefully soon be an audi owner as i'm looking for something more economical than my volvo v40 2.0t (23 mpg!!!) and 4WD so i can pull my lancia deltas round. 2.5 tdi would pull well, BUT i'd be using it for commuting 99% of the time so i am willing to take the hit on grunt for the better fuel economy. B5 A4 quattro 1.9 tdi it is then!
Been looking for the right one for a while and got a couple in mind, will post in the a4 section.
