Guys, it's not a rebadged anything. It does share parts with the all-new Ford Mondeo sedan, mainly the engine, but I have read that only around 20% of parts are shared. The steering, chassis, suspension, etc. are all heavily tweaked by Jaguar engineers, and the car is AWD instead of FWD like the Mondeo.
Plus, the Contour was based on the previous-generation Mondeo, and I believe the Lincoln LS shares a platform with the S-Type.
I haven't driven the X-Type yet, but the reviews I have read are quite good.
