i always felt the other way around! my tj was so uncomfortable in the back seat and had no space behind the seat it felt... the new ones have a usable space, and once actually in the back seat, there is a good amount of space.
my jeep has been on a construction site, a field and a drive in theater... that's about as off road as it's been! not at 10,000kms yet though, so it's still new to me... feel like i have to at least give it a year or so before basically intentionally damaging it.
i'd say 1-2% take these off roading... but about 15-30% do occasional things that need something tougher than a cuv... whether its their cottage is set back down a 300ft unkept path with occasional small trees down... they take pictures up in algonquin and need to know they can get down any logging road, etc.... they consult on construction sites and need the clearance to not damage the underside... they live in the country and they want to be confident that even without plows, they will always have the ability and clearance to get out of their driveway...
... all the rest like the look and feel... and hey.. .convertible!
how many "sports" cars actually get taken to the track? a similar % i would think.
cars aren't about "needs" often.. they are "wants"... otherwise, we would just have a pick-up truck, electric smart car, corolla and a grand caravan... pick one, because those four will do everything for everyone.
