If the sport was a short wheel base than it is going to be a rougher ride than an unlimited. You cannot compare a 2 door and 4 door as the same vehicle. Other than that I don't see any point in buying a JK Sahara. If it were a TJ than there are big enough differences to make it worth the extra money but not a JK. Just my opinion on it.
