I personally think TOTB is a fantastic idea. The problem is you have to keep the interest for people to compete. It would be a sad day that Cossies, RST's or indeed any car didn't enter because they basically had no chance. You need to encourage as varied a field as possible, so that everyone can see what is the best RST, R5, Scooby, Cossie, Skyline, etc, but that may involve making more classes. What about N/A? They can't compete with turbo cars, even the Vipers. Why not have 1.6, 2.0, 3.0 or unlimited, etc?
