Cons:
small gas tank. i get like 12 MPG, which i am sure the 4R does too if your loaded like i am but i have what seems like a 200 mile range....always pumping gas.
you cant see anything out of it. you get used to it. you feel for the rocks, that's what the skid plates are for.
you learn to back into any parking spot you can when given the opportunity. Reversing is a skill and the FJC forces you to get good at it.
it is the perfect size for you and your wife and one dog. if you utilize the roof rack properly. expect any more and it ain't happening. Kids- nope. and don't expect to sleep in it. i know people who do, but i don't because i am too tall. Solution: Roof top tent. The back seat is for the dog. its bigger then a 2dr wrangler, and a happy medium between the 2dr and the 4dr. BUT NOT A JK!
They are expensive. Resale is stoooopid. i am lucky i scored a certified used 2010 6MT back when they hadn't gone crazy and no one wanted the stick. the windshield is $600. Keep that in mind when buying used.
