The Alfa Romeo Montreal 105.64 represents the sole production generation of the Montreal, spanning the model's full 1970 to 1977 production run. Bodied as a 2+2 coupé and styled by Marcello Gandini at Bertone, it translated the well-received 1967 Expo concept into a road car built on Alfa Romeo's 105-series platform. The generation is mechanically notable for drawing on Alfa's motorsport program, using a detuned version of the V8 engine developed for the Tipo 33 racing car, a relative rarity for a road-going grand tourer of its era. Its combination of Italian coachbuilt styling, a racing-derived engine, and the cultural cachet of its Expo 67 debut origin story have kept the 105.64 consistently sought after among collectors.
