History of the 1958 Pontiac Bonneville:
The Pontiac Bonneville became its own line in 1958, having been promoted from a performance upgrade on the 1957 Star Chief. The 1958 Bonneville was built on the same chassis, but as a true performance model.
With this model being a candidate for the first true Pontiac muscle car, Bonneville buyers got a lot of power for their money. The base engine was a 370-cid, 255-hp V-8 with a Carter four-barrel carburetor and standard 3-speed manual transmission — or 285 horsepower with the optional Super Hydramatic automatic. Upgrade opportunities included Rochester fuel injection or a Tri-Power setup consisting of three Carter two-barrel carburetors, 10.5:1 compression heads, and a performance camshaft.
On the outside, the Pontiac Bonneville carries the same space-age styling as the rest of the 1958 Pontiac lineup. It’s an attractive car available in two-tone paint with plenty of chrome. Options are typical for a car of this era with amenities such as a foam seat, power everything, air conditioning, and so on. Unique to the Bonneville, buyers could order the car with bucket seats — another indicator of the proto-muscle car design.
Collectors considering the 1958 Pontiac Bonneville have a choice between the coupe and the convertible. Of the two, convertibles amounted to approximately a quarter of the total production of cars. Most of these cars were delivered with automatic transmission, although there is evidence that at least one car was built with a special four-on-the-floor transmission for Daytona racing. Collectors will want to search for well-optioned cars featuring Tri-Power or Rochester fuel injection.

Per Gooding & Company this car was acquired in the late 1990s by noted collector Jim Mangione who displayed it in his impressive collection of American classic cars. In 2001, Mr. Mangione sold this Bonneville convertible to Erich Traber of Switzerland, who probably kept the car within the US. In 2005 it was sold to another owner who thoroughly prepared the beautiful cosmetic presentation of the car. The car is currently coming out of an amazing Southern California Collection for the first time in many years where it has been well cared for and in good company.
