Due to the modular nature of "defenders" and commonality over the many years of production , at what point does the vehicle become more later model than early version ? The attraction to criminality , is due to the market , which can be very voracious , it leads to a big theft problem in UK , and greedy people in UK and US thinking the government agencies are fools . I have viewed many pics of US 90/110 (they have to be this model ) and thought even from the pics that there was no way they were the year mentioned. Many were no more than a late defender with different numbers applied to them . Landrovers are much more identifiable than most people realise, and LRUK cooperate readily with the agencies with build specific data . A lot more info as to year can be gathered from careful inspection of the vehicle components as it is with any vehicle. It is a pity that some possibly gullible , and some quite likely knowledgeable owners have now come unstuck . Its going to make the legit vehicles even more valuable tho !
