Ever since she was a teenager, Sandra Aguebor wanted to be a mechanic, a profession no woman in Nigeria had ever entered. Twenty years later, she's the successful owner of her own garage, and she's teaching other women the secrets of changing a tire and dropping an engine. For them, it's a chance to earn a steady income -- and status -- in a male-dominated society.

Sarah Simpson reports from Lagos.
