I have no idea how this thread became yet another GTR balancing discussion.

Quote from tailing :

Anyway to get back to the original post I'd be happy with any new cars, whether they're in a current class or totally new. I'd hate to hear that a potentially great car wasn't added to the game simply because it had no direct competitor though.

This poll only indicates there should probably be about two new class cars for each individual class car added to the game, and I'm sure the Devs have already decided what projects they are developing next.
By the way, which dev does modelling? Do we have any idea what they are doing?

Eric does all the track and car modelling but we usually don't get much indication of what he is working on.
