 Having owned the A4 now for just over a year, I thought it was time to give my impressions.  If you are looking for a red light racer, keep looking.  If you want a car that handles VERY well, accelerates good enough, but does so with a classy, polished feel, then this is a car you should check out.  The sport package gives the A4 a flat, smooth ride, balanced handling, and good cornering.  The AWD and ESP provides the driver with confidence in snowy, slushy, and icy conditions.  I average 33 mpg highway (at 70mph)/23 city stop and go.  Interior is superb with everything right where you want it.  If you are looking at BMW 3 series, Acura TL/TSX, or Infinity G35's, give the A4 a look, too.
