I'm not sure if any of the RR3 staff follow this forum but just in case I have a small suggestion.  It's great that now when you view the cars in your "garage" it tells you which events they are used in.  It would be even better if you could get the same info for cars you are considering purchasing.  I recently purchased the McLaren 765LT and was jazzed to see that it was used in four different series.  This was dumb luck since currently you only get this info after you own the car.
