I see an error. Not sure if it is related to the change.

Note the MK1 & 2 are numbers while 3 and 4 are roman numerals? Is there a reason for this or a slight oversight in coding?

Edit: now I see why. I believe the discrepancy comes from Bedford vs Vauxhall. Not sure now if a change is warranted.
