Hmmm. It's possible, although not probable.
Your car would be AWD, which is difficult to drift. You could break it loose, no doubt, but you couldn't really drift. And even if you COULD manage to do it, lacking an LSD is going to make this very difficult.

From what i've read, the A4s also seem to have some power-issues. This may or may not be true, but as a touring car, it's going to have weight issues. More than likely, to get a good drifter out of it you'd have to take out alot of your 'daily driver' comforts.

As an automatic, it will be even more difficult to drift, because you can't kick the clutch or control your shifts like you could in a Manual.

All these things combined mean that you likely won't be able to drift this car. However, if you want a good luxury/daily-driver drift car, might I suggest the Toyota Altezza, Cressida or Soarer? They are all luxury or midline vehicles, most of whom compete with BMW classes for quality, and are all known as good drift cars.

Finally, a word of caution against buyig a daily-driver to 'have fun drifting'. Drifting is a track sport, you shouldn't do it out on the streets because you are deliberately losing control of your vehicle. Racers can dodge traffic, drifters can really only blow the horn. And, drifting wears a car down. Tires and transmissions burn out quickly, and you will find yourself doing alot of 'routine maintainence' (rotating tires, balancing tires, changing oil, etc.) more often, to keep your vehicle on the road.
I'd buy a nice street car, and then go get a POS car to learn drifting in.
