That's another thing I've been looking for.... vehicle weight over time....

For the Impala... someone posted in another thread...

Year = pounds
1958 = 3,458-3,523
1959 = 3,570-3,665
1960 = 3,575-3,635
1961 = 3,445-3,600
1962 = 3,450-3,920
1963 = 3,265-3,870
1964 = 3,325-3,895
1965 = 3,385-4,005
1966 = 3,430-4,005
1967 = 3,455-3,990
1968 = 3,250-3,940
1969 = 3,640-4,285
1970 = 3,641-3,871
1971 = 3,391-4,021
1972 = 3,720-4,150 -- "In '72, Impala all-time sales topped the 10 million mark, extending its lead as the best-selling full-size car in automotive history"
1973 = 4,087-4,162
1974 = 4,167-4,256
1975 = 4,190-4,959
1976 = 4,175-4,972
1977 = 3,533-4,072 -- "curb weight was cut by more than 700 pounds"

the more current weights are
94-96: 4221lb
00-05: 3465lb

So the weight in 1958 is almost the same as 2005.... This could be isolated, but it strikes my interest strings


But ya, there's a lot missing (I totally agree)... I've got some other points, but If I post it all - I'm worried no one will say anything at all (I'm looking for different perspectives).
