My '88 Ranger had 195k on it when I swapped it. The little 2.3 still ran like a top, but the Mazda gearboxes those had was not up to snuff.
I have a '97 GMC 1500 4x4 with manual trans, it has 205k on it. I was hauling heavy loads with it last fall when we had to get all our stuff off the lease. Pulling my partner's tractor back, I was having to flog the crap out of it to keep it above 50 mph. Got all the way into his front yard with it and stopped in front of his barn. Damned thing wouldn't start anymore...turned out my coil control module and coil itself had failed. Replaced them and it's running strong again. Coulda been a real PITA if it had quit on me 30 or 40 miles out. The good Lord does see me through on many of my ventures.
Also have an '05 F150 Lariat with 155k on it. It's been a damned good truck and a nice ride.
