I agree about the quality of life, but my grandma bought a 1969 Chevelle new off the lot in Redding CA, and drove to my parents house by herself, she was 73 then. She kept driving and travelling until about 1976, and gave the car to my cousin in Redding. She was happy and healthy, cooked and darned socks, made afghans for fun and family. She was big, but tough. She had various furs and a mink coat given to her by a trapper for feeding him when he was broke. Ran the cookhouse at her families ranch, taught school, and ran the Post Office too. The really fat brothers wife, she lumbered and breathed hard.
Did she exceed the combined maximum GVWR? Maybe it had the specially optioned 454 supersport package?
