Think of it like buying a McDonalds meal. The staff all look the same with their little red acne ridden faces, special hats and blank expressions. How do I know I'm being served by one of the less retarded retards if I can't clearly see they've got the full compliment of stars on their little name badge?
Think of cosworths like McDonalds staff. Think of the colours like the star system.
Paint it pink.
Then we'll all know which one you are.
