Best option for a competition. Nobody wants Toyota alone in RC1. When there's enough WRC27 manus/builders, either RC1 will be reinstated or Rally2 gets deprecated, possibly both.
Toyota will likely win with their WRC27 Car (no change there). But at least there will be more brands of (Rally2) cars 'competing' with them in the top class.

I’ve been out in Myherina and Sweet Lamb today, there is a lot to love about rear drive, great sounding rally cars being driven well.
