For '06, the A4 retains its coolness, although to my eyes, not quite as much. The attractive "jelly-bean" body is still there, but the front-end treatment, in particular, detracts from the overall elegance of the car's styling.
With a definite family resemblance to the new Volkswagen Jetta, the A4's front end was apparently inspired by Audi's "Nuvolari" Quattro concept car. It's imposing and eye-catching, but somehow kind of superficial -- maybe it's just me, but I think they should have left well enough alone.
