Pontiac had a major change for the 1959 model year, the introduction of “Wide Track.” The front and rear tread dimensions were extended by more than four inches, putting the wheels closer to the corners of the car. This was accomplished by reducing side overhang, so that the they were not as narrow as the 1958s, but were no wider overall than the 1959 Cadillacs, Buicks, or Oldsmobiles. The common interpretation is that Wide Track was intended to improve handling, but those who worked on the design have a different story. Historians Jan Norbye and Jim Dunne have quoted Pontiac stylist Jack Humbert as saying that Wide Track was “to make it look right…it was a combination of having to put the wheels farther apart in order to give the car the right proportions.” Also in 1959, marked the first year of Pontiac’s split grille which was to become a trademark of the brand until its passing some 60 years later. A total of 11,426 top-of-the-line Bonneville convertibles were produced in 1959; far fewer with the Tri-power carburetion and bucket seats, such as seen with this car.

With luxurious appointments and a four-barrel V-8 as standard, the Bonnevilles for 1959 were Pontiac’s finest models. The elegant Convertibles, however, comprised less than 15 percent of total production. This particular Convertible has experienced just two owners (one for 53 years) and has been restored with its original features and is in remarkable condition. It features the desirable 389-cid V-8 with the three carb setup and dual exhaust, uncommon bucket seats, power brakes, steering and top; Wonder Bar AM radio, power antenna and spinner wheel covers. The Code A Regent Black exterior paint with the contrasting Code 95 tri-color blue interior makes this Bonneville stand out from the crowd.
