Thanks for all the input guys. I dont have any pics at the moment, but will try to take some. It's pretty much like simoncpw's but all silver with no black parts. And it has chrome handles and mirror trim. I bought these ones:

22 black rims wheels tires fit BMW 6 7 series 645 750 : eBay Motors (item 350309636186 end time Feb-24-10 22:19:08 PST)

They haven't shipped them yet, so I can prolly switch them out for some 20" or all silver ones, if they have any.
