What I hate about the 5th gen is the "high beltline." This trend started a few years ago with the Chrysler 300 and it's just gotten worse. It makes vehicles look fat because the lower body is huge and the 'greenhouse' (i.e., the part with the windows) is much smaller.
To me it makes cars look like they are in a comic book or cartoon.
Now, having said that, one thing about 4runners is that with factory-sized wheels and tires, they look odd. I guess Toyota must have realized that a lot of people put bigger tires on, so they make the fender wells extra large. Which is fine, but if the owners keep the stock, small wheels, they just look weird.
I saw a 3rd gen yesterday with stock sized wheels and even it looked odd to me, whereas a 3rd gen with a nice, slightly oversized wheel/tire combo looks awesome.
And I've noticed the same thing with the 5th gens. The ones with stock sized wheels look terrible (especially the limiteds with their hideous 20 inch "wagon wheels." Seriously, that's marginally OK on a car but on an SUV it just looks awful.)
But put some meatier tires on it and it looks pretty good, especially with a mild lift and an ARB or similar bumper.
