With the R36 I got a 10% corporate discount and then a further $2000 off by negotiation. With the CC I didn't get any corporate discount and had to negotiate from a much higher price. This will probably change in time. Also it was hard to see how far they would go on the CC without actually buying it. It will be useful to see how much people actually pay for it in the near future.
The CC has metallic paint as a $1000 option whilst it is standard on the R36. The CC also has more options available such as adaptive cruise control and park assist.
