Sears was popularly known as "Gentleman Jack". His son
David is also involved in motorsport. He won the inaugural
British Saloon Car Championship in 1958, driving an
Austin Westminster. After finishing on joint maximum points with
Tommy Sopwith, it was initially suggested the champion would be decided by the toss of a coin. The idea was very unpopular with both drivers and at the final meeting at
Brands Hatch, with a draw being a likely possibility, two identical looking Marcus Chambers-owned
Riley One-Point-Five works rally cars were brought along for a five lap shoot-out. To make the race fair, they raced five laps, switched cars, then raced five laps again with the driver who had the quickest combined time being crowned champion. In pouring rain, Sears became the first ever champion by 1.6 seconds. He regained the title in 1963, driving a variety of cars including a
Ford Cortina GT, a seven-litre
Ford Galaxie and a
Lotus Cortina, which was used for the final two races. Sears also co-drove a
Ferrari 330 LMB with
Mike Salmon to a fifth place in the
1963 Le Mans 24 Hours, the best result in the abbreviated racing history of the LMB.
AC Cobra In 1964 AC Cars decided to enter a works Cobra in that years
Le Mans 24 race and hired Sears as one of their drivers. To test its stability and gearing at the speeds the car (which had the chassis number A98) was expected to reach along the three mile long Mulsanne straight they decided to test it along the only available place that was long enough to reach its potential top speed. This was the northern end of the first section of the six lane M1 motorway which had no barriered central reservation and no speed limit. The use of the motorway for high speed testing was not unusual as Aston Martin, Jaguar and the Rootes Group had also using it. After Sears had some food at the Blue Boar service station and waiting beside it for no traffic to pass for several minutes he set off at about 4:15 am on 11 June 1964. With days after a conversation in a Fleet Street bar reports of the high speed run was headlines in the national newspapers. Tragically, the Cobra speared off into the barriers and killed three young French spectators who had been standing in a prohibited area. Baghetti was uninjured, and Bolton was taken to hospital with minor injuries. ==Death==
