I think they're at least breaking even and you need a separate brand for the higher warranty and other perks especially the Black Label models. It's not just the features but also the styling which justifies the higher ATPs. And it's also about supporting the dealers.
I think there are enough folks who want a Land Rover/G-Wagen type vehicle but want to buy American to make it work. Remember it's not just about Ford's bottom line but life support for dedicated dealers.
