IME, it's not the engine and transmission that cause headaches above 100,000. There's lots of other stuff that can and will go bad. Tolerance for dealing with that and the ability to get stuff fixed properly varies. Having a trusted mechanic or shop could sway the decision. I'm on the fence now with a 100,000 mile F150. Runs well, no rust, comfortable, etc. At my age I'll only be towing a couple more years. BUT.... I've had a water pump replacement that turned into a $1500 screw up. Later on a cracked radiator that I'm 99% sure was the Ford dealers fault, another $1000. I'm probably an idiot to keep going back to the dealer (I've tried two) but I don't seem to have another option. Financially it's surely better to keep fixing stuff for two more years as opposed to $50,000+ for a new truck, but having those two years w/o all this drama is appealing.
