I see that the plan is to go with the sport class again, myself (and i know others would) prefer to use the pro class. As an alternative to a team using one car for each season it could be an idea to change cars every race and force the teams to use all cars at least once each season. Skins could be done in any sponsors colour scheme as opposed to team colours, so it would maybe be more attractive to league sponsors. The team that scores the lowest points in one race could have first pick of the cars for the next race and so one. As a twist one car could be kept back for the final race of the season so if the last race is to decide the title then it could be held with all teams using the same brand of car to enable a level playing field for the championship decider. Just a few thoughts for the future.
