It's a great car in terms of interior and handling, very economical if you are thinking of getting a diesel. There have been horror stories though of people getting lemons(bad car) but most people I know that owns a Focus have no problems yet.
It's also an old car, soon to be replaced next year, so if it were me I wouldn't get one. If you really do need a new car by March, why not go and look at the Fiesta or the Cruze?
