Looking at a 2003 E-250, thoughts?
Along the way I elected to do several things like new A/C compressor etc, reman'd calipers, new rear brake cylinders, drums, front rotors, master cylinder just for reliability. Along with regular maintenance as well as changing spark plugs I can't complain one bit.
Currently running an '03 with the 5.4, also from an outfit that performed regular maintenance, even gave me the shop log of what's been done since it was new to them. It has 163K miles, put on the road in November of '12. So far it too has been a great van.
Long story short good maintenance on these Ford vans pays off and they make great second owner utility vehicles for anyone not needing a $32,000 + new van. (The '03 cost me $4,500 which was fair given its overall condition and features.)
Most good mechanics could test drive one for 5 miles and get a clear idea about it. Taking a drive monitor portable scanner along for the test drive would give a world of invaluable info. You'd be making an informed decision based on more than just a gut feeling.
Sounds like you're onto a potentially good deal though---how much are they asking for each of the E250's ??

Regardless I'm still driving it now with 300K miles but between the severe body rust and a few failing exhaust manifold studs it still runs just fine. It now sees about 350 miles a month on runs picking up supplies and parts for my windshield business.
