Doesn't look to bad. At least not compared to my old Dodge Prospect I bought while living up north.
Down here in the south rust is unheard of, which is odd I like 10 miles away from the largest body of saltwater on the planet.
Yeah I figured from a huge wheel gap it was a handicap van. Something about the dodges makes them get it done more than any other van. Do they still have rear leaf springs? I think I see one. That would explain the ease of modification, and this might not be structural. Yet since these are pricey and hard to find used, I'd be interested in taking the best care of this.
In Chrysler's defense, they made considerable improvement with corrosion protection by the mid-80s. This included galvanizing all panels, including the deck lids and roof, and not just the fenders and sides.
Any alterations after it leaves the factory, and the vehicle loses the factory applied corrosion protection, which cannot be duplicated at any shop.
