Newbie 4.8 M Sport owner - help pls

[TransientWolf]

Hi

Picking up 4.8 X5 M Sport this Saturday. Mind if I ask a couple questions - can't find answers searching:

1) It's a July 07 build - anybody know if this makes it a MY07 or a MY08 car?

2) Whilst messing when test driving it didn't have an option for the reversing camera to be in the main window with the PDC in the right hand window - does this indicate a MY07 car? And if it does will a software update make it available?

3) The Sport button behind the Auto stick didn't seem to do anything when I pressed it - like not only do nothing but didn't even light up (or couldnt see that it did). The car has the Adaptive Drive option - is that why?

4) I know the dealer won't upgrade the software without faults - can anybody tell me what software version would be on an 07/07 build, what the latest version is, what the changes are, if its worth getting, and what you think the cost would be in workshop time? (Sorry - rather anal)

Thanks. Appreciate your answers.
