yeah, i hate to press this point any more in this thread, so this is the last i'll say on these points...
if you can't derive vehicle dynamics from a 5 minute drive, that is a loss of man points for sure.
we're not talking livability, it takes time to find out things like how your knee eventually may not like the center divider, or what kind of weird vibrations the car may make with a certain combination of open and closed windows, or what a certain squeek means, but how a car handles? 5-15 minutes, no question. every car, of the hunderds i've driven, i knew exactly how they handled within that time frame. i may not know the absolute limits, but i can tell youwhether it will push, rotate, if the springs are soft/hard and thier relationship with the shocks, how quick and direct the steering is (or is not), what the tip in feels like on the throttle, whether the automatic transmission will be a willing partner or a pain in the butt, how nicely a manual's synchros work and how either is geared... etc, etc.
also, i love jeeps, they are fantastic at what they do, and no, i haven't driven the new 4dr, but, due to the revised suspension and longer wheelbase, i would assume it wouldn't porpoise like the older shorter models. that said, it is still a jeep, still 'trail rated' and will, almost by definition, have a driving dynamic that is different then a car, and i would put money on this, less comfortable than most cars on a long drive to a majority of people.
