Pontiac Grand Am specs: 1973-1975

Pontiac Grand Am specs: 1973-1975

The ’73-’75 Grand Am came as either a colonnade coupe or a colonnade sedan. However, a single Grand Am station wagon was produced as a prototype and still exists today. The overall purpose of the Grand Am was to bring Pontiac a model with European flare, and it’s no coincidence that it came out just as the GTO was starting to be phased out. The G/A was the first platform that showcased Pontiac’s ‘Radial Tuned Suspension’.
