About the Lotus 18
The 18 was Colin Chapman's first mid-engined design, built for Formula One, Formula Two and Formula Junior in 1960 with a heavily triangulated steel spaceframe, bolted-on lightweight panels and a semi-reclining driving position. In 2.5-litre form its Coventry Climax FPF produced 239 hp at 6,750 rpm, driving through a five-speed sequential gearbox developed from the Lotus 'Queerbox'. Innes Ireland gave Lotus its first Formula One victory in the non-championship Glover Trophy on 8 April 1960, and six weeks later Stirling Moss won the Monaco Grand Prix in Rob Walker's privately entered car. Moss won again at Monaco and the Nürburgring in 1961, while Ireland won the United States Grand Prix as Lotus finished second in the Constructors' Championship.

Rarity is a collectible game mechanic, not an assessment of real-world scarcity or value.
