Terry Horler worked in the aerospace industry and his engineering background has provided a useful background to his enthusiasm for cars, particularly Midgets and Sprites. He bought his first Sprite in 1969 and currently owns two Frogeye Sprites and a Sprite Mk IV. In 1983 he co-founded the Midget & Sprite Club, which now has over 1,000 current members and 5,000 historical memberships. He is a regular contributor to the club magazine Mascot. He has also contributed to articles for classic car journals. He is the author of other specialist books on the Midget and Sprite cars, focusing on practical and technical aspects.
