Thought about Radical but I reckon we'll get mini-LMP stuff anyway so I voted Ruf.
I don't like the style of the poll particularly. If they selected those brands then they have cars in mind, so they should have posted the specific models. Maybe they can't promise anything, but surely they're confident enough in at least a couple of cars from each of those if they're making this poll.
e.g Would I like a Group A Skyline R32? YES. Would I like a new GTR or Almera Tino? NO.
I'd like to see Assetto Corsa do Ruf properly, nobody else has. Not just the ones from GT4, but Yellowbird would be a given I'd hope.
