To me performance means more than just 0-60 or how many g's it will pull on the skidpad. It means a well balanced car with no real shortcomings. A car that has good brakes, with little dive and squat and that remains composed near the limits of handling.
Steering with good feedback and a well thought out suspension.
I've owned cars with much more power, and ones that will put down higher numbers on the skidpad. But on a twisty road I could probably get through a set of turns faster in this car. On top of that this one is just more fun to drive.
It's not a world beater, just a better drive. All of that and it has four doors...a sports car in disguise. For longer drives it's comfortable and gets good mileage. Some of the finer points are subtle and easy to take for granted..until you drive something else. You guys know what I mean. Yeah, its no M3 but day in and day out the 330 puts a smile on my face.
People always ask me if it was worth the $40k and if I would buy it again. In a heart beat.
