Convertible-only initially: The first generation Bonneville was initially only offered as a convertible, signifying its luxury and sporty intentions. This made it a highly desirable and exclusive model at the time.
Powerful V8 engines: Throughout much of its history, the Bonneville was known for its powerful V8 engines, providing ample performance for both cruising and spirited driving. This was a key selling point for many buyers.
Iconic styling: Each generation of the Bonneville had its own distinctive styling cues, making it easily recognizable and contributing to its enduring appeal. From the tailfins of the 50s to the aerodynamic lines of the 90s, the Bonneville always stood out.
Rarity and high cost of parts: Older Bonnevilles, particularly the first generation, are now rare and valuable, leading to higher costs for parts and restoration. This can be a significant consideration for potential buyers.
Rust susceptibility: Like many cars of its era, the Bonneville is susceptible to rust, especially in areas with harsh winters. Thoroughly inspect any potential purchase for rust damage.
Primitive safety features: Older Bonnevilles lack the advanced safety features found in modern cars, such as airbags and anti-lock brakes. This is an important consideration for safety-conscious buyers.
Full-size sedan, coupe, and convertible options: Expanding beyond the initial convertible offering, the Bonneville became available in a variety of body styles to appeal to a wider range of buyers. This versatility contributed to its popularity.
Rust susceptibility: Like many cars of its era, the Bonneville is susceptible to rust, especially in areas with harsh winters. Thoroughly inspect any potential purchase for rust damage.
Emissions controls becoming more complex: As emissions regulations became stricter, the Bonneville's emissions control systems became more complex and prone to issues. This can lead to maintenance headaches and reduced performance.
Significant size and weight: The fourth-generation Bonneville was particularly large and heavy, which negatively impacted fuel economy and handling. This is something to consider if you prefer a more nimble vehicle.
