Pontiac Bonneville

The Pontiac Bonneville began in 1957 as a limited-edition, fuel-injected convertible, establishing itself as Pontiac's top-of-the-line model. Through the 1960s, it embodied the brand's performance and style image, famous for its "Wide-Track" stance and available big-block V8s. Collectors gravitate toward these early models, especially convertibles and 2-door hardtops with desirable options like Tri-Power carburetion or the 421 Super Duty engine.

The market for Bonnevilles is extremely broad, reflecting its 48-year production run. Early convertibles and high-performance coupes from 1957-1968 command the highest values, often exceeding $75,000 for exceptional examples. Later generations from the late 1970s through 2005 are far more affordable, often trading as used cars rather than collectibles, but they represent an accessible entry point to the nameplate.

Prices range from $500 for late-model sedans to $148,500 for premier convertibles from the 1950s.
