Just keep in mind that the 4-door Unlimited is not a cool replacement for the family mini-van or CUV. Those rear doors are narrow and the floor is above what you are accustomed with. For example, trying to strap your child into their car seat will torque your back, only way to get around this is to climb in yourself to do the job. The ride isn't the best, the fuel mileage isn't very good, the reliability isn't great and trying to get warranty work will generally be a "challenge", even if you don't mind hanging out around dealerships. Explains why you are starting to see more and more of these units back on used lots and in the classifieds.
Don't get me wrong, I love my Jeep, but I use it off-road everyday to take my dogs out for their runs as well as to commute to work with it. But it really is a specialty vehicle. The 4 doors enable you to take along like-minded people who enjoy off-roading adventures. If you need a soccer mom type vehicle, better to buy one.
