MARKET ANALYSIS
Series 1 (1966 to 1969)

The Alfa Romeo Spider Series 1 debuted in 1966 at the Geneva Motor Show, serving as the purest expression of the Pininfarina-styled 105-series roadster until production shifted to the Series 2 in late 1969. Commonly referred to by the nicknames "Duetto," "Roundtail," or "Osso di Seppia" (Cuttlefish Bone), this front-engine, rear-wheel-drive roadster was initially powered by a 1.6L Twin Cam inline-four producing 80kW (109hp), before being joined by the entry-level 1300 Junior and the more powerful 1750 Spider Veloce, which delivered 87kW (118hp). All variants featured a five-speed manual transmission and four-wheel disc brakes as standard. In Australia, the Series 1 is considered a blue-chip classic due to its extreme rarity and the iconic status it gained via its role in The Graduate; consequently, it sits at the apex of the Spider desirability hierarchy. The buyer pool consists of high-end vintage collectors and dedicated "Alfisti" who prioritize the original 1960s aesthetic over the later, more common Kamm-tail models. Market values for the Series 1 have climbed steadily into the six-figure bracket, with pristine 1750 Veloce examples now commanding between $115,000 and $150,000 AUD, while well-restored 1600 "Duettos" typically trade between $85,000 and $110,000 AUD. Production of the Series 1 concluded in 1969 and it was replaced by the Alfa Romeo Spider
