1964 was the first year for the GTO, which technically was an option package for the Pontiac LeMans coupe. The LeMans was an intermediate-size car that should have been restricted to a maximum engine size of 330 cubic inches, based on GM's internal regulations. A car had to have 10 pounds of weight for every cube of displacement. DeLorean and his team got around GM's rulebook by offering the bigger engine as an option package. The 389-cubic-inch engine from the larger Grand Prix was swapped in and the GTO was born. The engine produced 340 horsepower and 428 pound-feet of torque when new. A three-speed manual was the base offering for the GTO.

In 1964, a total of 6,644 Pontiac GTO convertibles were produced. The GTO was also available as a hardtop (18,422 units) and a coupe (7,384 units), with a total production of 32,450 cars for the year. This example made $84k at Mecum.
