On the subject of Porker interiors .. at goodwood i sat in all of the 911's they had on the stand and the interior quality varies heavily, primarily due to spec.
The base model, with no real interior perks is a pretty bland cold and clinical cockpit, its definitely not luxury nor a 100k car feel. We actually all preferred the base boxter to it interestingly.
Comparatively, sitting in a fully specced 911 GTS .. wow, that's a 100k car interior. The extra leather, premium finishes and alcantara etc makes for a much more special place. First time ive actually really been affected by 'extended leather', usually it just seems like a waste of dough.
