buy a 130bhp golf for the money you sell the focus for, get it chipped to about 175bhp for about £450 and you'll have a car thats very very good!
or if you wanna spend a few ££ more the 2.0 tdci focus is a damn good car. but i think if it was my money a chipped golf would be for me. don't be too put off by them as standard though, they're not that quick.
