This car competed in the 1 hour long Historic Motor Racing News Gentlemen Drivers Sports Racing Challenge race at the Gold Cup meeting at Oulton Park in August 2005.
It's the 1965 Lola T70 Mk1 driven in the race by Frank Sytner and Simon Hadfield, and a note in the programme of the event says this about the car:
Debuted, unpainted, by David Hobbs at Goodwood in 1965, chassis SLXX/4 was also raced by Monte Shallet and road registered by a later owner. Reimported from the USA by Frank Sytner in 2003, it is probably the earliest T70 still racing. Chevrolet V8 engine packs a big punch in Eric Broadley-designed monocoque chassis.
The car that David Hobbs drove at Goodwood in 1965, though, was that of Harold Young Racing, which was chassis SL70/2. Chassis SL70/4 was returned to the factory soon after delivery to Hugh Dibley and the car was rebuilt using chassis SL70/7. The history of SL70/2 is told in this Bonhams auction offering.
Here's the car during the race at Britten's chicane leading the 1965 Elva Mk8 of David Clark and the 1963 Elva Mk7S of Ivan Scotti.
