I'm due to take delivery of one in a couple of weeks time and I've got a demonstrator for this weekend.
I've currently got an S3 that I'm selling to get the A4. These cars are obviously very different, however the A4 is good. Being a V6 diesel, it is very torquey and the performance is good, although not as quick as my S3.
The handling is pretty good considering that it is an Avant and the suspension and steering are notcieably softer than the S3.
Not looking forward to selling my S3, but the A4 3.0TDIQ is a good replacement.
You guys may be interested in the review of an A6 3.00 TDI in this months Audi Driver, it has been modified by Tunit, bhp upto 275 and torque to 380 lbs. 0-60 in a genuine 6.5 seconds! Similar power to the BMW 535D. /ubbthreads/images/graemlins/beerchug.gif
Tunit are superb, they have a very clever box that does a brilliant job. I have had one of theres on a BMW and thought it was great, then had it remapped by superchips and it felt no different really, if anything a bit more reserved.
