Invicta

The Buick Invicta (1959–1963) was a senior full-size Buick, slotting between the LeSabre and Electra. Best known for the rare 1962–1963 Wildcat two-door hardtop with bucket seats and console, which evolved into the standalone Wildcat for 1963 onward. The 401 and 425 nailhead V8s defined the powertrain options.
