Basically carryover models from the 1957 Cadillac, the 1958
featured quad headlights, smaller, straighter bumper
guards and a grille with "buttons" at the intersection of vertical
and horizontal members. As was the style at the time, the
car was laden with chrome. The fins were somewhat
smaller and chrome trim "fins" moved horizontally
from the sides of the headlights. Horsepower ratings were
increased to 310 for standard models and 335 for the Eldorado.
