I remember one at Stratstone when it was in it's old place.
I went at night time, and i could just see it's nose pointing out from the row of cars.
Somebody told me it was up for £275, 000.. that was in '99 or at least 3yrs ago.. i dunno how much prices have changed, and with such a specialist car, it is worth whatever you want to pay for it, or the amount that the owner will sell it for
