I bought my Jeep kind of knowing it'd be an experience. After a year of owning it I've replaced a lot of components, but I also bought a high mileage Jeep. If you're looking into buying one it's a good purchase. It is my favorite vehicle I've owned despite being less reliable than other cars I've owned.
Bought this very basic 4x4 last summer with 125k on the clock, and just grow more enthusiastic every day. Its not a luxury car, but is very tractable on-road and there is NO vehicle still in production in 2008 that can come anywhere close to matching it for balancing on-road manners and sheer offroad capability. Its also built like a tank and is unbelievably reliable. Important stuff just does not fail on this car. Fuel econ. is quite good in commuting. They're so common that they're almost forgotten- but just look around you in traffic some day and start counting, and note how many still look great. Then remember there hasn't been a new one built for 7 years. Take THAT, Toyota.
Ruggedness and reliability.
Just come up with a real replacement! The Liberty is OK, but gives up too much in offroad capability and is too complex for the gains in on-road manners. The FJ Cruiser is a plastic-encased joke, and the Escape/Tribute is a FWD pretending to be a 4x4. This is a totally empty market segment currently
