The three big areas I noticed on the '59 were:

-The driver door coming open on impact.
-The non colapsing steering column protruding into the dummy folding the steering wheel on his shoulder [[ouch!)
-The Bench seat becoming detached from the floor.

Whoa! Are we really taking our lives into our hands when we tool around an old car! My two old ones are a 1968 and 1974 which feature more safety updates then the '59.
