I get your point, but does it carry enough to be considered a wagon? The whole point of a wagon is to avoid getting a SUV while getting around the same utility. When the wagon is almost as large as an SUV, carries less than a SUV, but consumes fuel about the same as a SUV, then I don't like it. The EX and Venza come to mind about the things I brought up. Then again, I'm not sure how much you can put into both cars.
I kind of don't like the fact that it doesn't look long enough. I like wagons, and I really hate the fact that EX is round and bulbous when it could have been elongated just a little to make extra room available for hauling stuff. That's the same gripe I have about the Venza too. Could be longer.
