Yes a blog review is in the works, but possibly not this month.
The GL450 is great overall. Roomier than any midsize crossover SUV for sure. Good 3-across potential in the 2nd row. Third row is also roomier, with two pairs of the nicest LATCH anchors on any vehicle. Very powerful. Very quiet and comfortable, too. Great third row access and better thigh support in the third row than any midsize or small full size SUV I've driven. It's not nearly as big as a Suburban or Expedition XL, but probably just a hair bigger inside than a Buick Enclave or Infinit JX35. Not quite as big as a regular Expedition or Sequoia. It's natural competition would be the Audi Q7, which also looked great for kids at the auto show, but I haven't driven one.
Still not quite as nice as a minivan in terms of seating flexibility or third row comfort. Plus, while the handling was good for such a large, heavy vehicle, I find the Odyssey or most midsize crossovers to be more nimble and much more fuel efficient, too.
