I have my opinion on chassis numbers which is much the same as Absinth. I think it adds to the value of a van/ute if they match but it isnt the be all and end all to their identity. However if you say that then it opens the whole can of worms as to the sale of tags on their own. I dont agree with that at all. So i suppose that means that you need the correct chassis to be 100% legit. So....... where do you stand if your chassis is blank? In the same position as any sandmans that have had a chassis replacement and restamp that the owners are unaware of really. There must be heaps of them about.
Owners books and full history to me is the most reliable and therefore any vans/utes with that are the most valuable by a country mile.
