I owned a JK and I now own a TJ Rubicon. The JK is, well, horrid. The VSC is a constant aggravation going off in corners so much the tires cup. I tried to go to a larger tire and could not because the VSC became unpredictable and would sometimes go off when changing lanes and snatch the steering wheel. The engine was a gutless POC. No power and it began burning oil at 40,000 and stabilized it seems at 60,000 but still burned oil. The engine would not start sometimes unless I jiggled the shifter. The dash lights would occasionally all light up and go blank, the car would lurch and then everything return to normal. The top leaked bad. Lift kits, parts and accessories cost much more on average than for the TJ and as I said, unless you can defeat the VSC it is a challenge putting larger tires on the vehicle. The sheet metal is very thin. I think the front fenders (flanders) are hugely ugly. The door sill looks like a minivan entrance. The 2 dr, which I had, is too wide and out of proportion, the 4 door looks like a Model T, too long. I had engine work done to correct the oil burning, spent a ton of money trouble shooting the shifter jiggle, fixed it all and told it good bye. My new TJ is so much Jeepy, the JK is so much like a minivan.
