This is one tough little truck. This is my first vehicle and I have beaten on it even though it had 174,000 miles on it when I got it. Now it has about 190,000 and its still running like a champ! It only has a V6 so it is not very fast and I wish it had the 318 V8. Has very rarely let me down. Only parts that have failed are the power steering pump (was going out for a while after an accident early on in its life), the water pump and dirty sensors. Other than that, extremely reliable and very recommended. Never had a transmission problem either.
The whole thing, especially the body design, seats and stereo. The 4WD is especially fun even though it can't do much serious off roading since it is underpowered.
Make a more fuel efficent engine! I keep my foot out of it and the 3.9L Magnum V6 only gets 16 mpg. Even though it has a lot of miles on it I shouldn't have that crappy of mileage.
