New Groups and Categories

The Historic Commission regularly reviews existing groups and cut off dates and considers the possibility of the introduction of new groups for more recent cars.

New vehicle types will not normally be considered for inclusion within the 5th. Category until some 10/15 years have passed from the time of their competitive contemporary career.

However, in this regard it should not be assumed that any vehicle with a racing history that becomes superseded will automatically be considered for inclusion in the 5th Category.
