[4][5] While working for Ruston-Bucyrus demolishing World War II (WWII) air raid shelters in London, Uren met demolition contractor Charles Willment.
Later Uren and his brother Douglas started a contract plant hire business, leasing out heavy equipment.
In 1964 he made another appearance in the Monte Carlo Rally, driving with Constantine John Manussis in a Ford Cortina GT.
In 1959 he became champion in the second year of the BSCC driving an upgraded Zephyr with a Raymond Mays aluminium cylinder head fitted with triple carburettors in Group C, finishing ahead of the works Ford drivers.
[28][1] For the 1961 season Uren drove a GSM Delta sports racing car to several class wins.
[29][30] In 1963 Uren became the chairman of a committee formed by the British International Saloon Car Racing Drivers to represent the drivers' interests and concerns to other groups that included racing clubs, promoters, the automotive industry, and the Royal Automobile Club (R.A.C.).
In 1959 Uren was appointed Competition Manager for Ford of Britain's Dagenham Rally Team, originally on a consulting contract basis with a one year term.
It was hoped that success on the track would create publicity for Willment’s Ford agencies, and increase sales of its line of performance parts.
[24][23] The Galaxie was a lightweight full race 'R-Code' car prepared by Holman-Moody, with a four speed manual transmission and 7.0 L (427 cu in) V8 engine.
[37][38][39] While in the US to take delivery of the car Uren was taken for a demonstration drive at speed by Holman-Moody's driver "Fast Freddy" Lorenzen.
[23][3] Uren hired Jack Sears to drive the Galaxie, which ended Jaguar's dominance of the BSCC series.
[40][41] Over the course of several years the Willment team fielded a variety of cars that included AC Cobra roadsters, a Lola, Lotus 23 and Lotus 30 sportscars, an Elva Mark Seven, several Formula Three (F3) Lotuses, a Formula Two (F2) Brabham, a Formula One (F1) Brabham-BRM, and the specially built Willment Coupé based on plans for the Shelby Daytona coupe supplied to Willment by Shelby American with modifications by Frank Gardner, built on an unnumbered chassis bought from AC Cars and generally referred to as CSX2131.
[5][36][42] AC Cars built their own Cobra coupé to race at the 1964 24 Hours of Le Mans, and brought Uren in to manage the effort.
An uproar was caused in the British parliament when it was discovered that the team had done high-speed testing of the car on the M1 motorway during the early morning hours.
