Looking into buying a Land Rover but it seems a bit of a minefield! How important is it to have a VIN on the chassis? If a chassis is galvanised will it loose its VIN? I understand that if you replace the chassis and show evidence the old one was destroyed it is ok, but what about if the original chassis looses its VIN during repairing. Also, looking at the rules surrounding radically altered vehicles, would a series 3 built before the rules came in (1998) be exempt? Thanks.
