You won't find a sportier car in this price range. The stiff suspension and quick acceleration make this car a blast to drive. However, if you're looking for a luxurious, comfortable ride, you may want to consider a Civic because the stiff suspension in the M3 makes for a bumpy ride. I personally don't mind it because I bought the car for its superior handling and acceleration and so far I absolutely love the car.
Acceleration, handling, sporty feel.
For the price, I'm not sure what else could be added.
