Taken from a BCA thread

Eric & Karen Bernard, Buick collectors in Washington state, have e-mailed photos of their latest Buick. A car they had long admired and first became interested in two years ago, the Buick is a standard series Electra 4-door hardtop (model 4739). This car's roofline is an updated version of the GM "Flying Wing" design that first appeared on the corporation's 1959 models. In 1961, this roofline was utilized only by the Buick Electra, Olds 98, and Cadillac. Production of this style fell far below that of the Electra 4-door sedan (model 4719) or Electra 225 Riviera sedan (model 4839), both of which were built in a six-window style. It's a design that is seldom seen, even at the BCA National Meets.

The newly-acquired Electra joins Eric & Karen's very fine, original 1961 Invicta Custom coupe and Flight Pitch-equipped 1958 Century 2-door Riviera.
