Value of VX220

[hatatak]

Selling sep 2002 silver vx220. Owned since new. Standard with leather and otherwise unadulterated except turbo roof seal and tracker. FMDSH, 12674miles, weekend/summer use only, no track use(condition reflects all this). Needs new battery - on trickle charger as not used in winter.
I am finding it very difficult to get a feel for a fair price for this car from parker's/wisebuyers/the original dealer(£9000!) and even this site!
Anybody feel they know what this should be pitched at?
Thanks
