Ford Cougar in UK is obviously 99% the same car as Mercury Cougar, but it has no VIN if buying to import - plus of course RHD instead of LHD. So, with no VIN, be sure you know what you are going to have to deal with on the customs/import/registration side of things.
Call the UK DNA for advice. The USA dna in Maryland is a distributor for the actual UK firm but they are not the company themselves.
There was a yellow DNA 3sixty for sale on here recently - maybe from Virginia. Look through forum.
Good luck,
