While I was dead set on the CF roof, I have to say that on a Sparkling Graphite E92, it's not THAT important since the darker color kind of hides it anyway.
I'm sure you can come down a bit on the price. I didn't get that great of a deal on mine, but I really wanted CF roof, the car had all the options I wanted and was a 1 owner car. So is this one it seems like.
Maybe 37 if you can live with the sunroof?
