Nearly 30 cars will line up for the Heritage Grand Touring Car Challenge during the British F3/GT meeting at Snetterton (Norfolk) next weekend (July 15/16).The HGTCC is one of the leading race series in Britain for sports, saloon and GT cars from the 1960s and 1970s and a near capacity grid will contest a pair of 35-minute races at Snetterton. With the option of having two drivers per race, one or two cars will have three drivers during the course of the weekend.The season started in fine style at Oulton Park on Easter Monday with a race that turned into a tremendous battle between the Ford Mustang of David Yates/Graham Scarborough and the Morgan +8 of GT racer Oli Bryant. Eventually, after the Morgan was forced to make a second pit stop to attend to a flapping door, the Mustang won, but it had been a fine contest.From a fabulous 30-car entry at Donington in May, Scarborough again won after another classic battle with Bryant. "You must be fed up with the sight of our car," joked Yates to Bryant after a race when three-quarters of a second split them at the flag.However, the second race at Donington caught some of the very worst English spring weather and a superbly judged performance by Arthur Thurtle and Roger Bennington got Thurtle's new Camaro home ahead. The Camaro should suit Snetterton extremely well, so they will be all out for another victory. If the expected seasonal debut of the Andy Rouse/Pete Hall Camaro is confirmed, there could be two blue Chevvies at the front of the action! Interestingly, three drivers could share the Thurtle Camaro as Boysie Thurtle joins the driver line-up.Meanwhile, the Aston Martin challenge is considerable. Chris Scragg and Bob Searles/Tony Jardine are the main contenders with their magnificent V8s, while Roy McCarthy will share his very quick MGB GTV8 with his sons Russell and Spencer. Welcome newcomers to Class A of the Heritage grid include Pete Hallford (Chevrolet Camaro), Rikki and Joe Cann (Aston Martin DBS V8) and David Falkingham (Triumph TR7V8).The stunning Jaguar E Type of Peter Lloyd will start favourite for Class B, but faces a big challenge from the Jaguar XJS V12 of Robin and Zoe North as well as series newcomers Peter Thornton/Jon Day (Aston Martin DB4GT). The historic Lotus Elan 26R of Pat Thomas/Mike Youles lines up against the Renault Alpine of Bill Withey in Class C, while the ever-growing Class D field includes the very potent Ford Escort Mk1 of Nigel Vaulkhard and John Smirthwaite. Variety is the key in Class D as the cars range from the Rover SD1 of Chris Williams to the rapid Mini Cooper of Nathalie Boyd/John Rhodes.
