From memory when I was looking at 3200's, changes were made in the factory on late 2000's onwards, so a 2001 / 2002 registered car would probably have the improvements, Those were to the accelerate by wire system, brakes and steering, they were supposed to make the cars a bit easier to live with..!! The AC went a bit further with other improvements also..!! I don't think Xenons were ever fitted, not even to the AC, I think you can retro fit, although I put high intensity lamps in ours and they worked quite well..!!
