Yes, actually my SE also recommended painting the rear mid section, and it is something I’ll definitely consider for my green Macan on order (I’ll look out for cars which have it to get an idea). My current Macan is Night Blue and as you suggest doesn’t look like it would have particularly benefited from it.
My SE also suggested the pano roof for residual value, and I can see it’s a really popular option, but it’s not something that has particular appeal to me so not sure I can bring myself to stretch to one of those!
