Unless it comes with lifetime oil changes and a reputable "bumper to bumper" 5 year warranty, that price is WAY too high.
That said, if the dealer already suspects that you "love it", then you are going to have to work them down hard to something much more reasonable, and reasonable also partly depends on what you can afford.
More importantly, while low original miles on a used car is always good, you should know that anything made from, or including rubber or plastic, continues to degrade even when the vehicle is not being driven. That means a VERY close inspection of ALL of the suspension and driveline components and if there is any cracking or looseness on the bushings etc, you are looking at several thousand dollars in replacement parts and labor at the very least.
ALSO due to UV degradation, you will need to closely inspect ALL door gaskets and window seals for their integrity and while your there looking you may as well look at body panel alignment just to make sure that the Jeep has NOT been involved in a collision.
Dont forget about the tires...if they are older then 5 years, they will also likely need replacing.
The above statements are somewhat mitigated if you can ACCURATELY determine that the vehicle was garage kept while not being driven, but if it has been stored outside for most of its life, then fair warning that youll be looking at additional parts and repairs, even on an otherwise low mileage car.
And of course you already know that oem parts are getting harder to find for the great little trucks.
