I believe that the GS actually has more boot space than the NX with the seat ups so with kids in the back seat not a great bit of difference. I agree it's probably easier to get the kids in and out of the NX - from the the seats that is, not the boot! Not so sure how important AWD is as most SUV drivers only go off-roading when they park on the pavement!
I agree about the new E class. Maybe when I get bored with Lexus...................
Anyway, what is it with people these days? My parents bought up three strapping young lads in a Ford Anglia. To be fair though, it wasn't just the Anglia, they had a house too!
