4. Historic Vehicles:

Vehicles of 'historical interest' means a vehicle which is considered to be of historical interest to the UK, and which -

was manufactured, or registered, for the first time at least 30 years previously,
is of a type no longer in production, and
has been historically preserved or maintained in its original state and has not undergone substantial changes in the technical characteristics of its main components.
