I bought my 09 Wrangler Unlimited Sahara in June of 2009 and will be honest for the most part it was a great vehicle. It did what I needed it to do getting me wherever I needed to be, protecting my children and I when we were hit by a drunk driver from behind at nearly 40 miles per hour, and the touch screen radio with GPS and HDD were wonderful to have for getting to places and not having a vehicle cluttered with CD's. I rarely took my front top panels off but when I did everyone loved it (cant say how heavy or difficult the back portion was as I never removed it). My torque converter did go bad at 42K miles (thankfully I bought the lifetime warranty on the vehicle which in and of itself paid for the tranny issue), I had to replace the brakes at 65K miles with the rear passenger side shoe sticking and needing a-lot of work, the door hinge bushings were starting to go bad, and finally the O2 sensors (which there are 4 of) went bad twice. I did truly love the vehicle. Visibility was great, the ride was smooth for a 4x4 and it was easy to handle. My main reason for getting rid of it is that the gas mileage is lower than I would have liked and I travel a-lot. I never got more than 21 mpg on the highway (and roughly 50k of the 75k miles I put on it were highway). If you want a fun 4X4 and can get past the lack of mpg and a little less than desirable power the 2009 was a good vehicle (at least for me).
The Jeep is not fast and the fuel economy is poor. But the Jeep wrangler, regardless of the trim, is the best off road vehicle that I have ever drive. My first experience was in the jungles of Panama. I saw a Jeep wrangler assigned to the us embassy negotiating hard terrain. After that I promised I would get one.
I call this "the last car" because I will never drive anything else. That said, it is not a "car" as much as a street legal toy. A giant go-cart. The feeling of driving a jeep is incomparable, but certainly not for everyone. In fact, if you even have to debate whether you should; then you probably shouldn't. If you are comfortable, however, with the idea of changing a heavy stubborn top (hard or soft), having little freeway acceleration, and generally driving a giant go-cart; then this is the car for you! You have to be prepared to think of your Jeep as a street-legal toy to really appreciate it. (Also, get the manual transmission or just get yourself a minivan)
Read some of the reviews on this forum, and from what I understand most of them don't understand what they got themselves into. Please don't consider buying a jeep unless you understand your purchase. You aren't buying a luxury car, you are buying one of the finest off roading, highly versatile vehicles on the road today. People that complain about water leaks probably don't understand how to correctly install their top. All and all this is an awesome vehicle to own.
Problems from day 1, water leaks in like a river (hard top), can't be fixed and caused rust in only a few months. Underpowered, driven 4cly cars that have more power. Had a cracked radiator. Many electric problems, odometer not working, windows not working, doors locking on their own, and more. The seats will kill your back, very uncomfortable. Headlights are VERY poor, worthless if you do a lot of night driving. Bought brand new and this all happened in the first 4 months of having it. The only good thing to say about it is that it preforms well off road.
