Thanks for all the replies so far. Does give some food for thought.
@cjh ... Thanks for the info especially concerning the dash. The fully leather covered dash was something that very much impressed Mrs T and would make a really nice change from the nasty 'hard plastic but let's pretend its textured leather' of the X3.
The definite requirement is for the more luxurious interior over exterior looks, so I think it's now going to be a Prestige with pretty much all the options bolted on (except the rear entertainment system and Smokers Pack). Having a Panoramic Roof on my X3 (but opening and not fixed) I'm not that fussed about them to be honest, as I never open the sun screen but I assume that it will aid resale, and I don't think it can be optioned out with the Lux pack anyway.
So looks like Mrs T wins
but whatever we go for I'm happy.
Only annoyance is several of my friends have all made the same comment ... "It's a girl/WAGs car and not a proper Range Rover "
Presume that's the 'Beckham Effect'? I've yet to see a female driving one of the few that are on the road round here ...
