1970 Pontiac Grand Prix
The big news for 1970 was a special Hurst SSJ version, a semi-custom conversion with an electric sunroof, gold-colored wheels, and a Hurst shifter.

1970 Pontiac Grand Prix

With the overwhelming success from the previous year 1969 redesign, Pontiac essentially carried over with the basic design for the 1970 Grand Prix. With the exception from the previous year the grille itself now featured vertical slats, and vertical hash marks appeared on the front fenders just behind the front wheels. New interior upholstery patterns and the reintroduction of the bench seat consisted of most of the visual changes.

The big news for 1970 was a special Hurst SSJ version, a semi-custom conversion with an electric sunroof, gold-colored wheels, and a Hurst shifter. The SSJ started life as J models (the vinyl accent stripes on SJs were incompatible) built by Pontiac, than sent to Hurst. All 272 cars were painted either Starlight Black (code AA) or Cameo white (code CC) . Interiors were black, ivory, or sandlewood in cloth or all-Morrokide. Mandatory options included body-color Sport mirrors, G78 x 14 whitewalls and Rally II wheels. The Space-Saver spare and Ride & Handling package were recommended. After assembly, the cars were shipped to a Hurst plant in Southfield, Michigan where Frost Gold accents were applied to the hood, side windows, front of the roof, and Rally II wheels. A landau-style half-top (Antique white, white, or black) was installed, as was a steel electronically operated sunroof (similar to that used in the Cadillac Eldorado).

NOTES: The first letter of a two-letter paint code identifies the body color. The second letter identifies the roof color. (For example, the combination 28-10 on a Pontiac would indicate the body finished in Atoll Blue Metallic and the roof area in Polar White.) General Motors paint code plate for all models is located on the "horizontal" or "vertical" surface of the shroud upper panel on the left side of the body.
