Vast improvement? YES! Will they make it? No f'ing way! Hummers of every variety are practicaly glued to the showroom floor, and have been for some time. Hummer is not part of the General's "new way forward"....the H3 hit the market with a resounding thud, pretty much sealing the fate of the brand. You'll see a new Aztec before you see this in production. Shame too....looks like a Dakar Pajero on 'Roids. Drop in the new, lightweight LS3, add in the I/S and you get Baja beast (rather than rock crawler) Too badit's a very attractive, if essentially useless, design)
