The 1958 model year…
This 1958 Cadillac Eldorado Biarritz Convertible is a beautifully restored 1950s luxury icon and one of just 815 Eldorado Biarritz convertibles produced in 1958. As the top-of-the-line Cadillac convertible for the model year, the Biarritz combined dramatic styling, cutting-edge technology, and premium luxury appointments.
The 1958 model year was significant for Cadillac and General Motors. On February 7, 1958, Cadillac produced its two-millionth automobile, reaching that milestone just eight years after building its first million.

Industry-wide quad headlight setup
Larger, wider grille with distinctive cylindrical “cleats”
Relocated Dagmar bumper guards and parking lights
Refined side trim with five horizontal windsplits
Redesigned split rear bumper
Updated, more refined tailfins
