Pics might lie but, it doesn't look horrible?

Looks surprisingly complete - maybe the spare tire access panel is inside it.
Also looks like there's another '57 Dodge in one photo.

Bet the floors are toast, though.

With it sitting on the ground, one would have to wonder what condition that frame is in.

A 57 was the first year for the torsion bar suspension and the car had a full frame. My son has a 57 wagon like that car with a modern hemi in it. We stripped out his parts cars a few years ago. That one looks pretty complete and may be a great starting point, There are a lot of parts on those cars that are hard to come by that appear to be present on this one. Many things (like replacement windshield gaskets) are crap and pricy, they don't fit well at all.

For whatever its worth, my son loves his 57 wagon, not many are roaming the streets.

That one photo shows another 57 wagon, and a 2 door hardtop in the background! Pretty unusual to see that many of those cars at one gathering. I would be surprised if there are still front floor boards in any of the 57 cars. Dodge put a line of self tapping screws under the lower windshield trim to hold the trim on the car. Those screws were not sealed and the channel they were in was not even painted. The wagon my son has was a CA car that spent its entire life inside. That was how we found out about the trim screws, the area was still intact. The floors on it were perfect too! We had to cut them to open up the drive shaft tunnel enough to fit the 360 Magnum drive train that we first installed into the wagon. Broke my heart to cut virgin, rust free, floorboards!
