The 1977 Cadillac Eldorado Biarritz was also the brand’s most expensive model 40 years ago — before BMW, Mercedes, and Lexus stole the show. This is a 1977 Cadillac Eldorado Biarritz — one of the quirkiest cars I’ve ever reviewed. The Cadillac Eldorado is a luxury car manufactured and marketed by Cadillac from 1952 until 2002 over twelve generations. The Eldorado was at or near the top of the Cadillac line.

The original 1953 Eldorado convertible and the Eldorado Brougham models of 1957–1960 had distinct bodyshells and were the most expensive models that Cadillac offered those years. A convertible Eldorado was also offered for 1971, the first in the line since 1966. Door glass remained frameless, and the hardtop rear quarter windows were deleted, replaced by a fixed “opera window” in the widened “C” pillar. A stand-up wreath and crest hood ornament was new this year.
Inside, there was a new curved instrument panel and redesigned seats. A fiber-optic “lamp monitor” system, which displayed the functionality of the headlamps, taillamps, parking lamps, turn signals and brakelights was mounted on each front fender and the shelf below the rear window. This 126.3 in wheelbase version Eldorado would run through 1978, receiving major facelifts in 1973, 1974 and 1975. Sales in 1971 set a new record at 27,368.

The convertible was dropped (although Custom Coach of Lima, Ohio converted a few 1977 and 1978 Eldorados into convertibles using salvaged parts from earlier models). The mammoth 500 cu in. (8.2L) V8 of 1970–76 was replaced by a new 425 cu in. (7L) V8 with 180 bhp (134 kW) available in all 1977 Cadillacs.
