It's not too shabby. Not as butch looking as the E70 but a decent effort nonetheless. Back does remind me of the X3. Kinda prefer the E70 myself. In my opinion BMW done a better job with the new X5 vs old X5 than Merc did with the old ML vs new ML. New ML looks more like a stationwagon on stilts.
Prefer the e70 too- keep in mind though , that's the e70 with sport pack and 315s on the rear compared to the stock new shape.
You know what happens to Beemers when they sprinkle m sport dust on them
