its a bit harsh to say I`ve overpriced myself. You clearly have just googled a few on the net or ebay. The really immaculate ones (extremely rare nowdays that aren't refurbs ) are minimum £18k plus vat. You may find one a year come up for sale but most are collectors now or being mothballed until they can be exported to the US in a few years for big money.
Most on the net are rusty and are around £6k - £12 and may well be on a refurb engine hence no true odometer reading.
there are quite a few fake Wolfs on the net too. Chassis, brakes, axles, voltage, gearbox cooler, roll cage height etc are all very different to normal ex mod .
