Yes they do exist, my Disco 300TDi with it's knackered engine is going back to the guy that sold me it and he has agreed to a full refund and is even paying to transport it from Bradford to Surrey - result!!!
At least I haven't lost the £3k that I paid for it, or that was until I thought sod these old cars and put the money down as deposit for a Disco3 TDV6 :-)
