Efficiency is not everything for many when you can drive for 5 hours straight. If you can drive for 5 hours or 5:30 doesn't matter. A 20 minute difference at 10 hours/1000 km challenge doesn't matter. So then it is upt to preference: if the windows leak air, if the suspension is comfortable, the seats ar good, your knes kan have a bend, and you don't need to hear tire noise like an old Suzuki.Efficiency is absolute, not a question of preference. Nobody prefers low efficiency.
So it's not that simple. If somebody prefers a lower-efficiency car, it must have something else going for it, something that compensates. Something like a bigger frunk.
And for some, they really need that extra effiency and those supercharges that they use everey day.
