I've been all over the Katzkin website. I know about the premium & deluxe - just not sure which of those is most like the factory in terms of real leather panels vs. vinyl.
On a factory, isn't the upper rear seat, and all headrest faces made of leather?
Katzkin used to have a customization form on their website where you had some selections as to how much leather coverage. I no longer can find it there.
