Hi SilverSi
many congrats on the car - must admit I only joined the club last Saturday when I picked my E70 spec:

3.0 SD - Black Sapphire
Dynamic Pack (20" wheels)
Media Pack
Sunroof
Third Row Seating
Heated seats
Sun protection glass & rear blinds
USB
Folding Mirrors
Running Boards
Heads Up Display
Xenons

Love the car - but the economy (still early days - and being in stop start traffic) was not good.
Your right no torch - I think BMW started pulling these out (no pun intended) 2007, hence no contacts where the torch should go.

Yes your right those mirrors do not fold in when you hold the lock button - although this may be a programming thing (I have been told BMW Service depts can program that key to do anything and everything on the car), you could do this on my E90 3 series!

The drive and engine noise is nice.
Parking the thing is a thing to get used to, conscious of those alloys and the low profile tyres
The cost of a punctured run flats on the X5 is scary as well - as I had several on my old E90, they were only 18" tyres and they hurt

Hope you enjoy your new ride!!!!
