Agreed. I've been a passenger in plenty of them; many of them don't seem any bigger on the inside than a hatchback, with very similar boot space. It's all pointless, superficial bodywork that makes the demand for them seem even more egregious to me.
Have you been on a BMW X6? I swear there’s less interior space in it than in a 3-series, the trunk is almost at armpit level and a mazda 3 can load bigger things. Same for the mercedes GLC. They’re the contemporary version of the hummer.
