i considered both PP and ACC
in the end I didnt feel the ACC was worth the same price as the PP, given the PP model is classified as a separate model, not the basic model + an option. This brings a slightly higher retained value.
Also, I just felt the hardware the £980 was buying was worth it - everyone says you wont notice the e diff or the extra 10 BHP, but dont forget the PP has much larger front brakes (340mm v 310) and bigger calipers, and vented rather than solid rear discs.
I felt I would get much more use out of this hardware that the adaptive dampers, for the same cash..
