Fleetwood Cadillac History 1966

Fleetwood Cadillac Models & History 1966

Fleetwoodexterior trim and Fleetwood interior appointments enriched the cars in Cadillac’s high-dollar lineup. The first major restyling, since 1959, was seen on these models, as well as perimeter type frames. The new look brought the appearance of the big sedan and the limousine up to date, so that it matched the visual impression of other Cadillac lines. A big jump in sales for both regular production models, but not the commercial chassis, was the result.
