For what it is the Ranger is a great little truck. I have an '07 that I drive the wheels off of and its great. Good gas mileage, comfortable, cheap to buy and hauls more than a Focus. Yeah sure it has the same motor they've been using since the Pinto but hey its proven technology. It would be a shame to kill such a proven platform that has probably had the R&D costs paid off many times over already. Make upgrades to it if needed but keep it around, yeah its not the coolest vehicle in the world but from a utilitarian standpoint it can't be beat. Also, I'm not aware of any other "true" compact trucks even still being made. All the others have grown up into mid-sizes. I wish they'd put a small diesel in it like the old Isuzu P'up.
