The first Grand Prix was a Catalina hardtop coupe trimmed to standards similar to the larger top-line Bonneville, with a distinctive grille and taillights.
The bucket seats were upholstered in Morrokide vinyl, while nylon loop-blend carpeting covered the floor and lower door panels.
The center console-mounted transmission shifter included a storage compartment and a tachometer.
The rear bench seat included a center fold-down armrest and a speaker grille that could be made functional with the extra-cost Bi-Phonic rear speaker.
Included were a padded instrument panel, deluxe steering wheel, courtesy lights, and other features.

Base price was US$3,490.
The standard engine was the Bonneville's 303 hp (226 kW) 389 cu in (6.4 L) V8, which came with four-barrel carburetor and dual exhausts.
Tri-Power carburation (with three two-barrels) raised output to 318 hp (237 kW).
Two other high-performance 389s were offered, including a four-barrel version rated at 333 hp (248 kW) and a 348 hp (260 kW) Tri-Power.
Late in the model year a "street" version of the race-orientated 421 Pontiac offered in 1961-62 became available, but only in a four-barrel form rated at 320 hp (240 kW).
Pontiac also offered the 421 cu in (7 L) Super Duty with two four-barrel carburetors, rated at 405 hp (302 kW), as a US$2,250 option.
A three-speed manual transmission was standard, with a Borg-Warner T-10 four-speed with Hurst shifter and three-speed Roto Hydra-matic as options.
