One is two years old, the other is 5 years old.That is the most critical thing to consider.

The spec will obviously be a lot nicer on the Zetec than the edge, but none of us here can say if it is 'worth it' or not. For example, for myself and my wife, an absolute essential is heated seats, as we both have bad backs. To a lot of people, that doesn't matter at all, but to us, it's a critical point.

Sorry, but your friend has to make their own decisions, based on the car, the spec, the mileage, condition, service history, etc.

Think it's got to be the 2012 as it should have some of its manufacturers warranty left just in case something goes wrong.

Some of the zetec extras over the edge are cosmetic such as alloy wheels and bits of chrome.

Go for the 2012
