Nikki Evans is a car mechanic in London who used to be a librarian. She chose this career for the independence, to use her hands, and to learn how things work. She also felt that many people prefer a woman to repair their cars. Nikki had to attend a Skills Centre for 20 weeks to become certified as a car mechanic. At the center, she was the only woman among 400 men, and some men were rude to her because of her gender. Now, Nikki works as a freelance mechanic, which means she is self-employed and does not work for a company.
