All Good advice - we have kids (young) so agree with the seats getting dirty problem ..but still prefer the lighter colour interior .. the other option we have been thinking about is the plat bronze exterior colour as that seems to suit light interier pretty well and is not the typical black X5 that you see cruising around Melbourne. Love that white though

and you save $2k on paint that could go towards adap drive
I test drove a 4.8 yesterday just to get a feel ... once it revs it gets going but must admit for pottering around town I would predict the diesel is more responsive ..have not driven a d or sd yet so don't know ..but suspect you would have an excellent idea by now .. do you notice for example ..when wanting to accelerate from say 40km/h to 60 ..is there a difference level of response btw d and sd? this is where I think I'd be willing to pay the extra for sd ... must admit though when BMW recently updated the 3.0d to do 0-100km/h in 8.1 (was 8.6) I wonder if the difference btw the two was worth the money (as the sd only went from 7.2 down to 7.0 sec when they 'upt it' from 200 to 210kw etc) ....given you can get the 3.0d in non exec mode (base) it could save a lot of money (I dont want NAV etc)... and that money could fund adaptive drive .. thoughts?
