I have the 4Dr 2WD speed. I bought it when I turned 16 and it has been the best vehicle as far as reliability I've ever seen. I bought it with 128k in '02 and now, in '05, I have 172k on it. Oil leaks a little, but that is expected for a 10 year old car.
The inline 6 cylinder 4.0 engine pumps out plenty of power to pull anything. The cabin is perfect for a sound system, due to the fact that it is all open! I have a 2600 watt system now in the back.
Better gas mileage. I get about 18.5mpg on the highway. Make sure you have a strong tow hitch to prevent someone busting your gas tank if you get rear-ended.
