I have recently picked up a 56 plate super charged l322, so far the experience is not to good,subwfoofer does not work but the sales man told me he has "sat in the boot with one of his younger mechanics cd's"and it does work...he also says that the logic 7 system means you might not hear the sub speaker!!
we now have a thump on take up of drive which the dealer says they have no known issues with,however there are known problems with software and valve blocks giving these probs..
not good so far!!
