No rattles or repairs. I've had it on the track twice. Each time was a full day and there is still life in the P zeros! The car loves to be driven on the track hard. No break fade or overheating, it just wants more! On the street it is not high strung or difficult to drive but very smooth and easy. The stability control system in track mode is so liberal that I can't tell the difference from track mode and full off! The car sticks like it has glue on the tires but it does have snap over-steer and needs to be driven with respect if you intend to drive with the traction control in track mode of off (not!). The rear end can be very light and twitchy but that is part of what makes it exciting!
2) Power & Torque
3) Wonderful interior
It's just a very sexy and exciting and scary car to drive hard. When I slip into the drivers seat there is always a little bit of anxiety because the car will kill you if you don't drive it with respect!
They will be totally changing the XK now that the F Type is here, so why bother.
