Cadillac enjoyed its first 200,000-car year for calendar '66, breaking
the barrier by precisely 5001 units. A mild facelift brought a new front
bumper and grille, plus more integrated taillight housings. The 75 switched
to the new perimeter frame and was fully restyled for the first time since
1959. Variable-ratio power steering was a new option, as were carbon-cloth
seat heating pads. The Fleetwood Brougham became a separate model, still
more luxuriously trimmed than the plain-roof Sixty Special and priced
about $320 higher.
I. D. NUMBERS
Vehicle numbers were found on the left center pillar post.
The original engine serial number was the same as the vehicle identification number.
The numbering system was the same employed a year earlier with the second symbol changed to a "6" for
1966 model year.
All Eldorados now utilized the first two symbols "68" for their Style Number.
The Sixty-Special Brougham was now a separate model of the Fleetwood Series with a "P" Style Number
suffix applied.
