Not a very good review as the presenter didn't do her homework properly about comparing the car to other brands (at the same time)...
I disagree with her about the height of the GLA, I'm regularly parking next to Evoque's, A3's, X1's, etc and the GLA doesn't seem to be that much lower...
Nor would I call it a hatch back as when comparing it to the classic hatches you can see it's wider and higher with a bigger ground clearance (I don't think she actually saw the GLA next to a hatchback)... also just because the boot opens like a hatchback it doesn't mean you should compare it to one otherwise a lot of Porsche drivers wouldn't be happy...
I certainly wouldn't see a hatchback doing the off-road trips I've done recently, not unless it was being chased by the cops and driven by a car thief...
