I found a 92 7.3 IDI 4x4 with the ZF 5 speed for sale with only 90k original miles. The truck belongs to an older couple and looks basically as new as a 92' can look. They are asking $5500, is this a fair price considering the limited market up here in AK? Also is there anything in particular I should look for in a truck from this era with limited use. Your input is greatly appreciated as I am new to these trucks. I'm just looking for a gutless tractor that will last forever and get decent fuel mileage.
