You can't argue with the publicity he has drawn to rallying, regardless of people's opinion of him, so I think a national championship or ERC would do well to convince him to compete at that level. That's if competing 'for fun', which does not interest him, includes not being in the WRC at all. Let's not forget his track record in rallying pre-WRC - winning WRC2 and being highly competitive in ERC that same year proves he was at one time able to finish events and string good results together, rather than crashing in every leg of a rally.
