People have known about and have been trying to aquire the Scottish one for years so unless the owner has changed his mind I can't see it being sold any time soon.
Regarding the 6X6 example, when it was recovered from Pounds Yard they tried to pull it on one of the axles resulting the current list. Quite if they just ripped the spring hangers off one side of the chassis or did more serious damage (broken axle?) I cannot remember.
