It outsourced the manufacture of its cars to fellow Dereham company Breckland Technologies.
Leading Edge was established in 2002 by Paul Mickleburgh to market its first new car, the 190 and 240 RT in Europe and the US.
The receivers sold the tooling and inventory to neighbouring Breckland Technology Ltd, run by ex-Lotus engineer Mark Easton, who continued to manufacture the cars and sold them on to Leading Edge to distribute from the summer of July 2002 at a price of around £26,500.
Its open-top body was glassfibre, with an extruded aluminium central tub topped and tailed by tubular metal subframes and weighed only 763 kg (1,682 lb).
The 240 shared the same Nissan 2.0 L engined as the 190 RT, but with a higher output of 240 bhp (179 kW; 243 PS), producing an acceleration time of 4.4 seconds to 60mph.
