I've got a 4.8iS that I'm considering selling. It is black sapphire with black nappa leather. It currently has 44000 miles. I also purchased BMW's Extended Warranty AND Maintenance which are good to 6/100k. It's been meticulously maintained according to Mike Miller's (Tech Talk - Roundel) guidelines i.e. in addition to regular BMW paid for services it has had mid cycle oil changes every 6-7k miles, diff and transfer fluid changes. It's always garaged and cared for with Griot's hand washes and waxes ONLY.
I also have the BMW recommended winter wheels and a brand new set of Michelin Alpin tires. If you're interested let me know via email
blair780@aol.com and I can send you photos and further details on the service/options/history.
