I recently traded in my 2 door 6 speed Rubicon JK for a 4 door Automatic Rubicon JK. This was a case of the wife making me do it. Though she states that this is all my fault. The extra length is apparant from the beginning after driving the 2 door, but that doesn't last very long. You just can't turn as sharply into the parking spots like you used to. Having the extra doors is perfect when you are trying to get 4 people out of the rain in a hurry. Of course accessing the back seats is so much easier than the 2 door. As an example for how much room you have in the back, I carried five 35x12.50 BFG's in the back with the soft top still folded up underneath the Hardtop. I could have probably gotten six in there. The acceleration is a little weaker, but still impressive with the extra weight of the hard top and 4 door model. The 6 speed definately has the automatic beat with the low 1st gear. Gas mileage in the city is poor, 15mpg with the auto vs. 18mpg with the stick. On the freeway, the Auto's higher 4th gear beats the Sticks 6th gear, so you make up a little there. The average gas mileage indicator has had some updating to it. The accuracy is greatly improved over my 2 door.
