Whats it worth???????

I have a ten month old Lotus Elise S2 111s, in Silver with apporx 8000miles on the clock. in very good condition. The car is pritty much as standard and the only extras are:

Push Button Start
Nice Momo Steering Wheel (With the carbon bits on it)
Braided Brake Hoses/lines
Pagit pads.

What do you think its worth ??
Private Sale??
To Dealer??
