Cadillac Allante History 1990

Cadillac Allante Models & History 1990

The Allanté was available in two body styles for 1990. The Allanté convertible hardtop included both a convertible top and a removable all-aluminum hardtop. The new convertible was offered as a convertible only and did not include the hardtop. The standard and optional content of the two models was identical with the following exceptions: an analog instrument cluster was standard on the convertible and a no-cost option on the convertible hardtop. The digital instrument cluster standard on the convertible hardtop was an extra cost feature for the convertible. A pearl white exterior color was available at no charge on the convertible hardtop and an extra-cost option for the convertible.
