Just purchased my A3, and after driving about town a bit now, I can say with certainty that this is a unique ride. Just like BMWs seem to combine refinement with performance, this car does the same, with a bit more raw feeling, less cush. If you are even thinking about a BMW, or one of the many alternative, do not let the A3 slip your list, this car is great! It's like play toy that has all the creature comforts you could want.
Connection to the road and the car. Feeling like I'm driving something a bit more special than the other million 3 series out there.
Make more of the optional gear standard. Pricing gets a little unfun with too many options, and many of those options are becoming standard with other makers.
