The DVLA works in mysterious ways and it's pot luck what result you get.
A friend of mine has been trying to register a classic motorcycle for about six months. After numerous letters, phone calls and conflicting requirements (depending on who he spoke to) he's given up and sold the bike to a dealer.
I once sent in a letter explaining that one digit was incorrect on my motorcycle engine number.
I received a new V5, the error was still there but the engine number had been assigned to the frame !
Conversely I registered a classic car that had been imported more than twenty years ago but never registered. I was expecting all sorts of problems but it went straight through without a hitch.
