Interesting to see V8 offset their own title, by giving a way to play for keeps. I can't wait to see its winner. I have seen a bunch of hardcore fans race each other just to win a prize. I see V8 promoting their goods with a sort of baiting technique to lure customers into trying out their game. Still it attracts due to its affordable price.
