This T280 was sold new to Portuguese privateer racer Carlos Gaspar, who raced it with considerable success on the Iberian Peninsula. It is believed to have been subsequently sold to the Jolly Club and raced in international events during the 1973. In the following years, chassis HU04 was also raced by Jorg Zaborowski and eventually by Ray Mallock in the Thundersports Series during the early 1980s. In Mallock's colours, the car was displayed for many years in the fabulous Rosso Bianco museum before it was acquired by the current, French owner in 2007. Following a restoration to full running order, it has since been raced in the Classic Endurance Racing events and at the 2010 Le Mans Classic.

It was then sold to Dorset Foods and driven by Tony Birchenhough, Brian Joscelyne and Lee Kaye in 1973 events and this continued into 1974, when Claude Crespin joined the driving group, and 1975, when Ian Bracey became a regular driver. Each year the car was updated at the Lola factory to the latest specification and different chassis plates were added to ensure it gained the best possible prize money. The car was raced at Le Mans in 1976 and in 1978 until 1980 and continued to race in Internationals right up to 1983.
It was then sold to Nick Mason and stored until brought back to Le Mans for demonstration runs in 1992 and 1993. Tony Birchenough, head of the Dorset Racing Associates, now cares for the car and it appeared at the Le Mans Classic in 2002, 2004 and 2006.

      The G.R.D. (Group Racing Developments) was founded in late 1971 by a group of ex. Lotus employees when it stopped producing racing cars for sale to customers. Main man was Mike Warner who set up his own facilities in Norfolk (East of England), capable of producing high quality Formula 3 and Sports cars. The Swiss Jo Maquart was hired as the designer, and the experienced John Miles, a former official Lotus driver was the main test driver. Several names immediately became famous behind the wheel of the “well-born” GRDs: Roger Williamson, Torn Walkinshaw, Andy Sutcliffe, Alan Jones, Dave Walker, Tony Brise, Jorg Obermoser (who would later build the TOJ prototypes based on the GRD) , the Japanese Tetsuo Ikuzawa and Hirochi Kazato or the Portuguese Jorge Pinhol, who raced in F3 in England (GRD 372) in 1972 without much success. 
Later, Obermoser bought the largest part of GRD to start his own cars: Toy Racing cars.
