As I've mentioned before, his management contacted Toyota after Finland and he was rejected.
When Ogier first tested he wanted something around 8 million to drive for Toyota and offered to help them develop the car since he felt it needed a ton of work. His arrogance actually offended the team along with Akio himself. They also feel he will not fit well with the Japanese/Finnish mentality.
I would not be surprised if he is offering to develop the C3 (perfect opportunity considering their misfortunes) in return for good money, but Citroen might not have boat loads of development money on top of Ogiers salary.
On a side note, the C3 is doing a lot better after more tweaks. Lets see how Meeke and Breen do in Wales.
