Matthew Wilson is considering IRC for next year if he can't get the budget together for WRC.
Judging by comments he has made previously, I think that he thinks he could fight for wins in IRC but in reality I think he would be out of his depth.
However I do think it could be good for him as a driver as it might force him to up his game as he couldn't plod around 5-6 minutes off the pace and still pick up 5th places quite easily.
