A 1959 Jaguar XK150 Drophead Coupé that has been comprehensively restored and substantially upgraded to improve performance and reliability. Acquired in already-restored condition from a US dealer in 2015 and subsequently brought to the UK, the car was subjected to a further thorough programme of works overseen by an independent XK specialist. Notable enhancements include an enlarged 3.8-litre engine conversion, a five-speed Borg Warner automatic transmission, electric power steering, and a rebuilt front suspension and rear axle, all documented in an extensive history file.
