The Bert Hadley Championship is divided into Road and Track Cars, they all need to be based on Austin Seven Cars (see the regulations for more details). Road Cars need to be fully road legal, Track Cars can also be road legal but generally they are modified for speed and are no longer road legal, compare the two Ulster Cars below.
