Your logic basically means every single manufacture that does rally today is in the same boat, you can't possibly name a manufacturer that would of stayed in rally as long as them with the limited success they really got out of those years. They have nothing to prove commitment wise in rally I'm pretty sure they have proven that commitment over anyone else.
Just admit you don't like Ford it's fair enough, but your illogical points over their apparent lack of commitment in rally make no sense, that is pretty much their trademark historically.
Never said I don't like Ford, just the operation of Motorsports, it's not illogical. And I explained other manufactures actually join series either due to relevant rules, or overall package being accessible and more fair than other series. WRC has always been accessible at times with Group B perhaps being the most expensive. So no they're not in the same boat with Ford
Citereon decided to take a break and build up for the new rules package but made sure they were in an earshot of WRC, and while they waited went to take on a new challenge in WTCC.
Toyota won, for a few years, while racing in an expensive series and nearly winning the major prize of that. Then decided to take on a new challenge that would be the most expensive yet, thus fiscally couldn't really run WRC on a competitive level. When that didn't work out they basically have come back to doing what they did before F1, running Sports Cars and now Rallying.
Hyundai really didn't have an international presence anyways until about the last few years which is why they finally have dipped their toes on a large stage racing wise. Not sure how this is at all comparable.
What did Ford do after they left?
The point you seem to miss, or as usual try to pick a fight out of when you clearly don't understand me (Peter Brock Holden cool wall comes to mind). Is that Ford to me is fly by night, they don't seem to put nearly the same effort as other manufactures do when they join, and when it doesn't work out they leave and just keep it domestic because that's where their product sells anyways.
