I couldn't work out which model it was. They all look the same to me, like so many recent cars! I suppose young puzzlers think all 1950s F1 cars look the same. I can't tell an Audi from a Porsche from a Toyota when it comes to LMP cars.
I quickly checked the BRC site but the pictures wouldn't load. I'll modify the title when I get a chance.
Thanks.
PS Looking through all images of Bango cars, I agree that this is most likely a CM05 Evo. Later cars had a different nose treatment.
