This is a question for all of you people who are in the know. I was just reading an article on Speedcafe that the Australian GT series is expecting a 30 car field next year, with a lot of newcomers. There was subsequent debate in the comments about how much cheaper they are than the current V8's. Seeing that the GT's cost around $600k for a newer spec "front runner", it still aint cheap. I know that COTF costs have blown out, but what is their real cost?
