Tried the Gordon Murray Rocket, tops out in 5th gear at 213km/h, bouncing off the rev limiter for ages at Bathurst, don't think it's a good choice. Even though it's MR, it's pretty hard to get the tail out. I think we would need something with 600pp plus, it also didn't feel very fast tbh, also tried the X-Box R and Caterham Seven, both were better in terms of gearing, but I think a faster car is needed. I'd love to see the Forumula granturismo as the car but I know this will probably be a unpopular choice. Aside from that I'm sure any of the GT3 cars will be great cars to race (SLS, M3, Z4)
I think we'll be doing a lot of Holden racing at the mountain. I'd be happy with it as a Season car but would also like: '14 Corvette '13 Ford Shelby Mustang '14 BMW M4
Great option. My vote will go here. Easily affordable. Not everyone will be able to have hundreds of thousands of $$$ free so early in the game. (unless you sit on the game 24/7) Personally would prefer a race car of some description so this seems perfect.
Regardless, hopefully it will make it to the testing stage and we'll see what the opinions are. If it were closer to 500pp it might be a bit more popular.
