in regards to all the arguing, I am ok with whatever Furi decides, its his series.
but in real BTCC there are many teams that run the same kind of car so why not here also? I understand the desire to have a diverse field, but in real life there are only 2 MG6's in BTCC and I think only 2 Ford's but many BMWs, Hondas, etc. So perhaps tweaking the system (and I am merely thinking out loud, not trying to step on anyone's toes) so that it ensures that there will be at least 2 of each car represented, so keep the 5 teams that must have 1 of the 5 cars, then let the 'Independents' choose any car, but give the option of being classified as a full team with teammates, or being a single independent driver. Possibly limiting the amount of the same type of car to 3 for the independents, so maybe you will get 3 extra Nissans and 3 extra Fords.
This gives the possibility of having 8 total teams and satisfying some of the disgruntled people, will also ensuring a diverse field of cars.
Anyway however you do it is fine with me Furi, I'm here to race đź‘Ť
