After the VW Golf and the VW Polo, the Opel Corsa is the third most popular car model in Germany. Around 107,000 of them were bought in the country in 2009 alone.When it decided to revamp the best-seller, Opel focussed on extending the range of motors available and optimizing the chassis. We took the new Corsa out for a spin to see if it really is more fun to drive now.
