This car was the 63rd XK 150 Roadster built and sold new with optional chrome wire wheels. Special equipment extras included fog lamps, a dual exhaust system and square-pad disc brakes. The engine was fitted with a straight-port “Gold Top” cylinder head, lead and bronze bearings and a lightened flywheel.
Originally supplied by Henley’s Ltd of West Hounslow to the first owner, R.A. Hellmuth, on March 7, 1960, OTS999 was finished in Old English White with a red leather cockpit.
OTS999 was subsequently sold in 1965 to its second owner, Mr. Chandler of Hertford, who in 1972 enlisted the Caxton Engineering Company to re-cellulose the car and re-chrome the radiator grille, rear bumper, headlamp surrounds, windscreen moldings, motifs and exterior components. He sold the car in March 1972 to a Mr. Ballisat, who shortly thereafter passed it to a Mr. Woodley of Cardiff on August 17, 1973, with mileage reading 32,560.
Mr. Woodley was a keen enthusiast who owned the car for many years. In August 1976, he was invited by the Jaguar Drivers Club and Thoroughbred & Classic Cars magazine to display the car at the national classic car concours at Weston Park. Just one month later, OTS999 earned the XK 150 Champion Concours Cup at an XK day at Sudeley Castle and then went on to win numerous other concours awards, including a first in the JDC Concours d’Elegance at Paignton, Devon. Mr. Woodley was a fastidious owner and kept close records of maintenance work, journeys and mileage, which remain within the history file.
In February 1999, Mr. Woodley sold OTS999 to Mr. Hughes of Hampshire, who sent the car to Richard Galvani of Cambridge Motorsport in March 1999. Work included reconditioning of the steering rack, an unleaded conversion, rebuilding the front suspension, a new starter motor, a new alternator, replacement rear-brake calipers and pads, Aeroquip brake lines, a new radiator and a new exhaust system. In April 2000, the Jaguar returned to Cambridge Motorsport for an engine and gearbox rebuild. and in 2002, Mr. Hughes instructed Cambridge Motorsport to sell the Jaguar. A Mr. Pressland acquired it in August 2002.
Marque specialists Guy Broad were commissioned to rebuild the cylinder head and replace the brake master cylinder and the front and rear brake pads. The vendor acquired OTS999 in December 2006 and immediately fitted tracking and battery charging systems. In July 2010, Guy Broad rebuilt the engine, and it is understood to perform extremely well.
