Yeah - c'mon Graham.
I've wracked my brains and even read the rules on the BRCA website but still not any clearer.
Are you querying the fact that it may not be commercially available (section 22.4) or that it isn't a reasonable representation of full size cars generally accepted as being suitable for Rallycross, Rallying, Trail and Desert races (22.1)
Or is it that you don't like Alec's paint job - in which case rule 22.8 could be invoked
I did wonder about the tinted windows - but I don't think that is a requirement within BRCA - but maybe for EFRA?
Or is it, as Tony suggests, the fact that Alec has not cut his body short enough at the front so technically, you consider the body to be the most forward protruding part of the car and is thus the bumper, in which case rule 23.2 may be contentious since it does not have rounded edges and corners?
I don't mind a puzzle but shed some more light please...
