Buick Electra : 1960

Prior to 1959, the Roadmaster and the Limited constituted the upper echelon of Buick's lineup.

For 1959, they were renamed the Electra and the Electra 225 respectively.

The Electra 225 nameplate was a nod to the car's overall length of 225 in (5,715 mm), earning it the street name "deuce and a quarter."

The Electra 225 Riviera was the top-line model and it shared its six window hardtop roofline with the Cadillac Fleetwood. Buick had been using the "Riviera" name to indicate a premium trimmed hardtop body style beginning with the 1949 model year.

A standard four-door hardtop and a two-door convertible were available, along with a stripped chassis of which 144 were built in 1959 and 1960.

Second generation.
1961-1964. The Electra, along with the LeSabre, was redesigned for 1961 with drastically shrunken fins.

Third generation.
1965-1970. All GM passenger vehicles received a major restyling in 1965. For 1965, Buick changed its marketing strategy and offering the Electra 225 in two trim levels, base and Custom.

Fourth generation.
1971-1976. All Electra 225s were hardtops in the 1971 to 1973 model years, eliminating the previous 4-door pillared sedan variant and the convertible. In 1974 Buick adopted GM's pillared coupe body and fitted it with the "Landau" option on the Electra Limited coupe.
