The top of the door cards are vinyl, unless you have the premium leather upgrade. But I have been using Bowdens Leather Love on my vinyl door tops without any issues for the last couple of years.
Yup - a separate issue, but one that has happened with just about every car I've ever owned.... Does anyone know of a 'not awful looking' sacrificial cover/film/adaptor that can sit on the area adjacent to the window, where your elbow ends up resting? I suppose the alternative is to hit up the wreckers and have a spare tucked away ready for the day it gets too worn to be liveable with... I've done a quick google, but other than some rather naff boxes that drop into the handle area to take a mobile phone (that look pretty rubbish to me), I've not found anything obvious. It's one of those areas that really rewards aiming off.
