Seen this on ebay and thought that if you turned it around so the vent is facing your front window it would look like the creative sports bonnet. And its only £25.
You would need a bit of work done on blending it etc but could be made to look fairly similar to the CS one IMHO.

If you look at the guys other bits he's got some bits that could be used to give the look of some other bonnets.

Use your imagination, I know its not the exact same as having the real thing but it might be an option for those that cant afford to pay a few hundred for the genuine article in these recessionary times.
