To be honest id be surprised if it sold for more than £3200. I dont think it looks battered at all. Cometic paint flaking happens to alot of machines. Personally if i had this unit on ebay i would have rubbed down and repinted the areas that had paint flaking from it. Anyone looking at buying a truckmount second hand will very rarely know the true history of it. Its a gamble you take, Looks can be deceiving.
