My sister bought a Grand Cherokee, and its floaty and disconnected qualities really reminded me of feeling less-than-great in minivans and SUVs in the past. Whenever I ride in something comparatively stiff like a Miata, Corvette, or Z4 I have no problems whatsoever. I grew up in somewhat sporty compacts so that may be it, but I rode in an awful Sebring a good bit which is not exactly a zero-pitch corner carver.
