I have to say, a boot full of stuff and two people in the car add just enough weight to turn the Z into a comfy ol bus.. thoroughly enjoyed the several hundred miles I've done (though forgetting my glasses and driving in the dark and rain was a very bad idea). Fully laden the Z is very comfy... a darn sight better ride than when empty with just me in it, which can get a bit harsh. Perhaps I need to put on more weight or do a clarkson and put a slab in the boot!
