Amazing handling, great build, great interior features and quality construction inside (instead of the cheap plastics of American muscle cars). Everything including the dashboard and door panels are high quality durable leather. Roof and some panels are all full premium suede. Yes cornering may not be as great as a true 2 door sports car. But it can beat any other sports sedan out there in cornering. If you want to improve cornering and stability to a large extent, like me go for something like a Dinan suspension, struts, light weight wheels etc.
Everything about the car. Luxury, performance, stability all in one. A real wolf in sheep's clothing.
Better cup holders. At this cornering ability and high speeds, the coffee and drinks will fly in the car without proper holders. I don't carry any drinks except tightly capped bottles when I'm driving ;-). A bit more console space storage would be nice.
