If you include a 'scratch built' event, you'd need to define 'scratch built'.

To some, 'scratch built' means built from scratch i.e. home made chassis or car bodyshell.  In days gone by that meant brass chassis and wood carved or fibreglass molded bodyshells.

To some, painting a white kit isn't 'scratch built'.

To me personally, 'scratch built' means you've made some part of the car yourself or clearly modified a standard part to suit a different car.
