I'm about to buy a van for my painting business in Portland, OR (been working out of my truck until now) No mechanical knowledge, so I'm trying to get a feel for what I'm getting myself into. Been searching used Econolines, about the '95 to '08 range. I see than most vans that have more than 200k miles have had work put into them. I found an '03 econoline with 126k miles for a good price (4,800) , asked if there's been any work put into it and they said no, aside from fluid maintenance. Which leads me to believe there could be a host of things I'll have to get replaced or repaired in the next 50k miles or so. Could anyone with work van knowledge give a rundown of when certain systems start to fail on econoline vans so I have some educated questions to ask sellers? Thank you!
