hehe i agree where i live theres far too many speed bumps, the smaller the wheels the better. I Think 16's will do me just fine, just gotta decide whether to pay the extra 200 pounds for the sony unit. It looks great in the car, has more speakers and mp3 which most of my music collection is on nowadays! The only thing that stops me is whether eventually ford may offer to install the aux cable to the ford 6000 unit at a cost Think i am going to sleep on it and phone tomorrow if I decide to go for it. Wish they could have thrown it in with the car :lol:
