It's just Ford turning a negative situation into a possible feeder for new sales. The first generation Windstars had a lot of problems. We had one that we bought from those crap used dealers that up and blew a headgasket when we hit a bump after 200k of abuse. I learned to drive in that blue van. I didn't hear about the rust issues and the recalls until after the fact.
If Ford offers you a good deal for it, that's the safest bet IMHO. It's not going to be easy to sell a vehicle with that kind of damage but it depends on the expensive of repairing it.
Really depends on your situation though.
