Simple low capacity high-output petrol cars seem to be most in demand currently. The Ford Fiesta and Focus, VW Golf, Vauxhall Corsa, Nissan Qashqai, Mercedes A-Class, Mini Cooper, Toyota Yaris, Kia Sportage and the VW Polo make up the Top 10 according to Auto Express's analysis of UK registrations.
