1960 Cooper Monaco T57 Mk II

CM3-60racingUnited Kingdom
Engine
Coventry Climax FPF 1253

A Cooper Monaco Mk II sports-racer, chassis CM3-60, notable for having been updated in period — following an early 1960 racing accident — by the Cooper factory to incorporate the more advanced coil-spring rear suspension of the later Mk III specification, a fact corroborated by a letter signed by John Cooper. The car spent over four decades in the hands of Cooper specialist Sid Hoole and has compiled a strong historic-racing record, including a class victory at the Goodwood Stirling Moss Trophy in 2014. Fully rebuilt prior to the 2018 sale by specialist Martin Stretton, including a fresh Coventry Climax 2.0 FPF engine.
