I've had a few dealings with pre-facelift models that were exported new to the far east, Malaysia or Singapore I think, then imported into the United Kingdom as used cars, but been given the wrong age related plates & recorded as new, when registered at DVLA. I know this can happen, my A4 was registered in Northern Ireland in Jan 1999, but when I registered it at DVLA in 2001, they cocked up, it was given a age related plate, but they recorded it as a new vehicle, so when I get insurance quote or give the reg number for parts etc, it shows up as a 2001 model.
I'm not saying this is the case for this one, but DVLA do make mistakes.
