SEBRING SPRITE -- This fabulous high performance version of the Austin-Healey Sprite was first introduced in 1959 as a small, fast grand touring car with exceptional road holding and braking, to effectively cope with modern traffic conditions and high speed Motorway travel. Since that time, many owners have regularly used their Sebring Sprites in all forms of competition with outstanding results, and indeed, the name is derived from three successive class victories in the International Sebring G.T. and Sports Car races held annually in Florida. 

While the majority of Sebring Sprites are used in exhilarating personal transport, The Toy Shop/British Speedwell Racing is naturally aware that many are also in constant use for race and rally, and with this competetive requirement in mind, the cars have been fully recognized by the F.I.A. as standard production Grand Touring Cars. 

Sebring modifications can be carried out to customers own cars - or to our own vehicles for purchase. The comprehensive specification, with choice of six stages of engine tune ranging from 65 to 120 hp can be varied to suit the individual tastes and requirements of the owner and this includes such items as interior trim, color, instrumentation, stereo system, lighting, final drive ratios and safety belts.
