they are the detuned 3.0 litre so pretty much bullet proof.
well spec too, iDrive Pro, heated seats etc
Only thing its missing is Xenons!

Service pack includes all and everything that pops up on the iDrive for 5 years. My dads service pack on the E60 covered fuel filters in everything.

If he buys, first thing to do is go a BMW dealer with the key and ask if anything is outstanding on the service pack as sometimes they will miss things.
