Production by year

Cars built per model year. The bars are rounded totals without station wagons, except 1969, which by Wikipedia's figure includes the Kingswood wagons. Chevrolet recorded production by series and engine, for all its big cars together, so these are not exact counts. The 1965 bar includes 40,393 sport sedans with the Caprice option; from 1966 the Caprice is a series of its own.

Wheelbase 119 in throughout: GM's 1966 kit for 1966, Consumer Guide for 1965 and Wikipedia for every year. GM's kits give lengths, widths and weights per model in tables our OCR cannot read reliably, so they are left out.
