My first car was a 950cc Mk2 Fiesta. Have an Elise, Zed and Volvo and keep moving between them is wwhat keeps it interesting. Volvo eats miles, quiet and got all the bells, Zed crushes the miles (at pace! ) and gives the big grin, Elise is nimble and a 'great drive' in that it's got that racing car feel to it all the time. Lucky I think, but each one has it's merits.
Try the Corsa for a week and a) see if you don't need a chiropractor or; don't want to push into oncoming traffic compared to your Zed.
