Extended leather is awesome, you just need the leather door handles now. I really want a leather upper and lower dash for mine but they were exceptionally rare on uk models.
I have never seen the doorcards for sale without being part of an M5 interior package and I'm not keen on going for a complete M5 interior because I doubt I'd find one in the condition I want, sadly.
I still have the vinyly stuff on the armest - BMW do a leather armrest with stitching to match the console but at £250 it's a tad excessive so I'm going to ask a few local leather places if they can recover it for me.
