Lexus LS 460 crowned the most high-tech vehicle
There is no S Class sold in the US with "upholstery." The standard interior is leather and if you have the Premier Leather (which I do) you have Nappa leather on the seating surfaces instead of the standard leather. Tecnically the interior is Sahara Beige/Cashmere.
I don't know where you get your info but you had better recheck your source.
Actually Jack the 804 leather code on your car is not nappa, it is semi-aniline leather which is higher quality than nappa.
