I'm in the process of ordering my Q4. I asked for "extended leather" (code Q212) which the Price List shows at $1,150. I was first told that to get extended leather, I had to also order the Sport Package - which makes no mention of leather at all. When I pushed back, I was then told that I could forgo the Sport Package, if I added the Luxury Package, which includes "extended premium leather," for an additional $2,990. Is there a difference between "extended leather" and "extended premium leather"? Has anyone been able to get just the "extended leather" without having to order an additional package? Thanks very much.
