That GT3 world cup idea has me excited. America should run the BMW Z4 GT3...

. Here's what I was thinking with the current cars and known to be available next season:
America, Dodge Viper
Britain, Aston Martin Vantage
Germany, Mercedes SLS
Italy, Ferrari 458
France, Mclaren 650S
Japan, Nissan GTR
Belgium, Porsche 911
Spain, Lamborghini Gallardo
Sweden, Ginetta G56
Russia, Audi R8
Canada, Bentley Continental GT
Brazil, BMW Z4
Argentina, Lexus RCF
Mexico, Chevy Camaro
Finland, Audi R8
Netherlands, BMW Z4
Austrailia, Nissan GTR
New Zealand, Ginetta G56
Austria, Porsche 911
Switzerland, Mclaren 650S
South Korea, Lexus RCF
Dubai, Bentley Continental GT
Course that's literally probably nothing like what it would be lol.
*Revised. If everyone had two cars this would be a 44 car field. O_O
