Eldorado Cadillac Models & History 1958
TheBrougham’s astronomical price was unchanged, but the timing of such a price proved to be ill-advised in this deep recession year. Sales production was a mere 304 units.
The major change for the Eldorado Brougham was seen inside the car. The interior upper door panels were now finished in leather instead of the metal finish used in 1957. New wheel covers also appeared. Forty-four trim combinations were available, along with fifteen special monotone paint colors. This was the last year for domestic production of the handbuilt Brougham at Cadillac’s Detroit factory, as future manufacturing of the special bodies was to be done by Pininfarina of Turin, Italy.
