If it was me I would go evo as I know loads of mates who had them and love them . Mk1 focus are a good car and I loved ours .
You will get a evo8 fq300 for around £8000 and prob a mk1 focus for £6000-£8000 depending on condition .

They all different cars and do different things , I know the evo are bad on fuel but so is the focus with a heavy right foot

I would love a evo 5/6 if me though .
