Hi Brad,
I agree with you and I was not very keen on the interior color of my CSI when I bought it either. It has however grown on me and I like more and more. I like the fact it is an Individual version ordered by BMW M I must confess that considering the car's good shape, I would have bought it even if it had a pink interior!
From what I've read, only one CSI was produced in Technoviolett from a total of 13 cars produced. The other ones where 8 840s and 4 "normal" 850s.
Regards,
