it is mot the year they are registered it is the year they
were built so a 72/73 car could have been built in 71
if you go through the tracability dept they can tell you
when the car came off the production line and where
in the country it was sent and i think the dealer it went
too.
if you get the certificate to show when it was built and it is tax
exempt you can have its taxation class changed to classic
