Can't say i've seen multifunction steering wheel as stock, so that's a mod. I'd check it has been done right as there can be airbag issues that can really put a dent in your day.
Odd you don't have the colour screen sat nav as i thought that a stock item on the S8 facelift. You also have what looks to be the sport mode gearbox (PRNDS rather than PRND432) which would make it late 2002 or it would in the UK from what i've read.....stateside may be different.
The drivers seat looks well worn and it could really do with a clean and shine.
I've not seen that colour often and generally i'm glad about it
