If you go for an X5, stay away from the Xdrive 30D as its too under-powered IMO for such a BIG car.
30d = 3.0 single turbo diesel
35d = 3.0 twin turbo diesel
40d = 3.0 twin turbo diesel (different map, injectors etc)
M50d = 3.0 triple turbo diesel
I have just got rid of my 2008 3.0sd (which is the pre-facelift 35d)... it was mapped to 350bhp & 700NM !!!
PROs
Looks great, plush interior, road presence, surprisingly fast
CONs
Too big for alot of car parks, heavy - so poor mpg, DPF issues, mega expensive runflat tyres (rears were 325/35/r20 @ £600 for a pair!)
Just my 2peneth tho.. for a buyers guide take a look at www.xdrivers.co.uk
