Yes, the Celica and Delta are Rally cars and not touring cars. But Toyota Supra is also a rally car. And Toyota Corolla Levin AE86 is also an Group A Race Car, but the AE86 was also homologated as a rally car.
240RS is Group B as well, road cars there is many because the formula is based off mainstream Road cars so that is not an issue but race car wise I think what I have put is the only Group A race cars.
