Hi dave,
H
Have you heard anything yet? My Nova was changed on the V5 to Nova Mk 4 so it has been registered as 1998. I rang up DVLA and they said I need to get a letter of age from owners club (Club Nova) and send that off with old V5 with tax classation change section filled out as Historical and a MOT (they must be able to just check this online) and the tax application form.
