Sometimes they can leak, if you dont install the tops correctly. Ive had mine leak twice but it wasnt bad, far less than leaving your windows open. I just reset the top if it does. I dont blame the jeep its my incorrect installation.
The jeep has more interior room than the fj and 4 full doors. It was important to me since i have kids. Also i didnt like the visibility the fj had, very closed in. Fj's do have great resale but so do jeeps.
The 3.8l jeeps kinda suck but the 2012+ pentastar 3.6 jeeps got a major improvement.
Could say f it and get a 800hp chevy 2500
Jeep resale and reliability is no where near that of an FJ but i will concede that the unlimited does have a FULL 4 doors and more room for passengers. Since I have one baby I am not too concerned for now since it is used sparingly during the week due to commute to DT Atlanta. Visibility...meh I could see someones complaint there until I just became much better using my mirrors properly instead of how I had conditioned myself to in another car.
