92 4 door 4x4. bought in feb. of 07 with just under 94,000. Now has almost 120,000 miles. Got it for $2000 with licence and all from a used car lot. It would spit and sputter on acceleration. Turns out the spark plug wires were out of firing order. Replaced the dying 100 amp alt with a 140 amp. Replaced the radiator, oil lines, that's all its really needed. I love my truck!!!
