Its occurred to me that what a pointless excercise that was. Did they really believe that after exhuming a car buried for 50 years it would be in perfect condition?? All that faith in a few plastic bags!
One has to ask, 50 years ago, what were they thinking?????
They thought (wrongly) the sarcophagus would be water-tight. Apparently there were dessicants and rust-proofing treatments in there that would have preserved it if the container hadn't leaked. The burial was a marketing stunt to get the town and the car into the news (the conceit being that the car was so futuristic it wouldn't look out of place in 2007, when the town would be celebrating its 100th anniversary).

If it doesn't work, you're not hitting it with a big enough hammer.
