These 180s are probably the least desireable '50s Mercedes from a restoration standpoint, but that said, they aren't exactly common anymore, and there are people out there that appreciate their '50s charm and utilitarian simplicity.
You might consider saving any chrome trim, bumpers, etc that are still in good shape, but as Florida is a near-tropical region, practically surrounded by salt-water, if the car is very rusty, chances are the chrome is shot too.

Happy Motoring, Mark
