Spice began his British Saloon Car Championship career racing Minis in the late 1960s, initially for Downton Engineering. He went on to paid drives with Jim Whitehouse's Equipe Arden team in 1968 and raced alongside Steve Neal in John Cooper's team Minis in 1969. Despite his pace and occasional race wins, Spice and his teammates were outclassed by the Broadspeed Ford Escorts competing in the 1300cc class.
His career fortunes changed when he graduated to the works Ford team, CC Developments, co-run by Dave Cook, where he drove the Capri 3.0S. Between 1976 and 1980 he won his class on five occasions, accumulating 24 overall race victories across his saloon car career. He never won the championship outright, however — in 1980, when he took on Andy Rouse as a teammate, the pair dominated their class only to lose out on the overall title to Win Percy.
In the 1980s, Spice shifted focus to endurance racing and established Spice Engineering in partnership with fellow racing driver Ray Bellm. The team competed in the World Endurance Championship, fielding its own cars as well as machinery from Jean Rondeau's operation. The enterprise bore its greatest fruit in 1988, when Spice Engineering secured the C2 class title in the World Championship — a significant achievement for a small independent constructor operating in the shadow of major factory programmes.
Spice Engineering became a recognisable presence at Le Mans and on the world endurance circuit throughout the decade, building and developing prototype sports cars that carried the Spice name. The team's work in the C2 category represented a model of how a privateer constructor could compete effectively at international level.
Alongside his motorsport career, Spice was active in retail commerce. In 1971 he co-founded Gordon Spice Cash and Carry with his brother Derek, a motor accessories wholesale business that grew to operate cash-and-carry depots in Staines, Watford, Canning Town, and Leicester. The company was floated as a public limited company in 1986, but over-ambitious investment in a central distribution centre, combined with shifting market conditions, led to its eventual collapse.
Earlier in his career he had also run a car accessory shop in Ashford, Middlesex, at a time when such retail operations were still a novelty in Britain.
Gordon Spice's career spanned two distinct chapters: a long and competitive run in British saloon car racing built around the Ford Capri, and a later chapter as a constructor-entrant in world-class endurance racing. His C2 World Championship title in 1988 stands as the high point of Spice Engineering's competitive record. He died on 10 September 2021 from cancer, aged 81.
