That helps a little Enzo - we can see that it still has an MOT history visible on the UK DVLA site which might mean it's not been recorded as permanently exported. If you still have the UK registration document it may be possible to bring it back into the UK on a trailer with that number plate attached and avoid any issues with VAT on export/import? That may make it more attractive to UK buyers? Do you still have the Uk V5 registration document?
