If you wanted a really rare 8 Series - Get an Alpina B12 5.7!
Super Bling! Hehe.. Nah as with all BMW Motorsport developed cars the 8 Series CS models are not cheap to run - but if you have the money to purchase one as if you can't afford to service one!
I'm not really that sure about the aftermarket for 8's.. But if you had a wad of cash lying around turbocharging wouldn't be out of the question! I'd love to see a force fed V8/V12 8 Series on the forums someday!
