1966 CADILLAC ELDORADO

1966 Cadillac Eldorado Little change was evident for 1966, the final season for the rear-drive Eldorado. This was a record sales year for Cadillac, its fifth in a row, and 1966 Eldorado production was exceeded only by the 1955 total. And that's as it should be, for a car with such a great heritage should end on a note of triumph.

But by now, Cadillac had decided it was again time for something truly new. It appeared the following year in the form of the first front-wheel-drive Eldorado, which would set a new standard for personal-luxury transportation. This car would only strengthen Cadillac's dominance in the upper end of the market. In first-year sales alone it exceeded its predecessor's combined total for the previous 10.

With the best of everything Cadillac had to offer in those years, they left an indelible impression in the minds and hearts of owners and would-be owners everywhere, and you can't ask much more than that.

FLEETWOOD ELDORADO SUB-SERIES 684

Fleetwood type trim was seen again on the Eldorado. Equipment additions included white sidewall tires and a six-way power front bench seat. It was to be the last season that conventional engineering characterized this model.
