Ummm....Very hard to price I would imagine. The Stradale is easier but this is rare and not many come up for sale. Not a fan with the black carbon bonnet.
The local dealer had a GT in with that colour scheme. It looked the business. The GC though is a tourer first so it doesn't look quite right. Price is difficult as there aren't going to be many of them. Sadly at that price would it get driven?
Would prefer the bonnet to be the same colour as the rest of the car as it looks stunning but for £100k why not invest in more photos before putting it up for sale and why EBay?
