[IF you compare Toyota & mitsubishi With Ford pick up I think toyota & mitsubishi are the cheapest in maintainace and Reliability.]
Ford, especially FORD RANGER, 2400CC double cabin, is the cheapest amongst its like. Its spares are readily available, though not cheaper.
The procurement officers in GoK would only check the initial cost and not the running cost, when buying for their staff. I used a CMC FORD RANGER 4X4 DOUBLE CAB 2400CC for 18months in my last project, and would tell you that GOK makes a big blunder, if we argue from an operation point of view!
