I saw a funny video of a 1953 DeSoto and a 1978 Camaro 60 MPH head-on wreck. The Camaro folded to 3 feet shorter, the DeSoto's hood emblem fell off.
Long, long ago someone asked "why are newer cars so easily damaged in a low speed collision?"
The answer: the exact point in time that GM changed the sheet metal gauge used for fenders, hoods etc. was known, it went something like this.
1930 16 gauge
1950 18 gauge
1970 20 gauge
