I bought a 3 year old 2010 XK Convertible in Indigo with the Cashmere interior. It had 25,000+ miles but looked and drove like brand new. I had a 2 day trip from Detroit, where I bought the car, back to DFW, Texas. The responsiveness of the throttle is simply amazing...even with "only" 385hp.. LOL. The fit and finish are outstanding. The suspension is a bit firm, but I guess that's the price you have to pay for such performance and handling. I generally get 18mpg on my commute to work and got 22+mpg on the road trip in from Michigan. The sat radio does seem to drop out quicker than my Lexus, but the audio response of the Bowers and Wilkins system is amazing. Truly a great car.
With traction control on, the car stumbles for a half-beat then digs in and goes! Upshifts are quick and pretty harsh. The car is still accelerating hard at the end of the quarter-mile. With traction control off, it's very difficult to launch, with tire spin at both the bottom and top of 1st gear.
Noisy racket coming from front suspension (not ABS controller), but straight and consistently short stops. Minimal dive with firm pedal.
Slalom: Blazingly quick turn-in and good front bite. Somewhat stiffly damped in "Dynamic" mode, which makes it unhappy with the dip in the track. Feels grippy but not trustworthy, like a Corvette, with an edgy personality in the rear. Requires delicate throttle control to maintain control. Skid pad: Given the "twitchy" feeling in the slalom, I was surprised at the amount of understeer on the skid pad. Good, but not great, grip with slightly vague steering info. Big difference between stability control on and off.
