What is a 1966 Alfa Romeo Spider Duetto worth today?

The Duetto launched Alfa's most enduring design, with Pininfarina's flowing lines remaining virtually unchanged for over two decades. The original 1.6-liter twin-cam produced 109 horsepower, providing spirited performance wrapped in timeless Italian elegance. With 6,325 built during the first generation, the Duetto established the archetypal Italian roadster formula. The distinctive 'boat-tail' rear end and perfect proportions make it the most desirable Spider variant among collectors. Graduate immortalized the design in popular culture, but the Duetto's appeal transcends Hollywood. Rust remains the primary concern, making solid examples increasingly valuable. Original cars with matching numbers and proper colors command strong prices. The Duetto represents the purest expression of Alfa's spider philosophy, combining mechanical excellence with Pininfarina's masterful styling.
