In WTCR they don't allow official manufacturer entry and look how close it is and how much drivers are from many different teams with many more brands. This year in World RX it's been quite awesome to watch with no works teams and still most of the fastest guys at the wheel, just by privateer teams. It could work here too. Hyundai have good promotion with their i30 and their straight away title for an example throught satellite team. Just make a car and enter with a team and that's it.
