I bought mine 10 years ago from someone who thought it only had 94k miles on it. But in changing the tranny filter I saw that the flywheel had been repositioned, and there were -two- well worn areas where the starter would hit the flywheel ring: Therefore I assumed it had 194,000 on it. It has the 350 with TBI, & the 4 speed auto trans. Now it has 264,000, and is beginning to show its age, with leaks around the windshield. I replaced the fuel pump when my daughter was going to drive it on a 4000 mile vacation to Mexico - during which trip nothing went wrong. I had to replace the engine temp sensor once & the spark plugs a couple of times. The alternator seized up on a zero degree day in northern Wisconsin, & I fixed that myself at the side of the road. I had to replace the output shaft seal on the transmission - which turned out to be fairly easy too. When first I got it I replaced the radiator, fan clutch, water pump, and hoses, & serpentine belt tensioner pulley; as pre-emptive repairs. Its a conversion van with the 3rdseat/bed combo, and has long since paid for itself just in the number of times we have slept at Walmart (instead of motels) while on cross country drives.
I had the main computer quit on us in the middle of a trip across Texas; it would crank over but not restart, after gassing up at a Valero station. I had been carrying a spare computer for years, so I swapped it in and we were on our way again.
Since we bought it, no one other than myself has worked on it, and it has yet to fail to get us where we wanted to arrive by the end of the day.
