This sounds similar to Argentine Turismo Nacional (
www.apat.org.ar). They have two classes numbered 2 and 3 for B-segment (Corsa, Fiesta, Clio, 206, Gol) and C-segment (Astra, Focus, Civic, C4) touring cars. Their tagline is "your car also races", since the cars not only are very stock, they also look more stock than TC2000s.
