It looks like the Willys is going to be a cheaper version ($71,990) than the Moab ($82,585). It appears that you won't be able to order the Willys until March, and that may mean you have a few months to wait for delivery.
I wasn't able to find a good a good comparison between the Willys and the Moab. I'd wager that the Moab has full lockers, but I'm not sure about the Willys. My son's Willys has a limited slip in the rear, which may be what the continue with.
