I think its all about What you want. And how and where and how often you drive the car.
Reasons i bought the Z in no order.
1. History of Z line
2. Looks damn good inside and out
3. Looks damn fast standing still
4. Turns heads everywhere you go. Everyday someone will ask you about it

5. Oh and imho the car is plenty quick or fast enough for any kind of driving.
