Well I should be selling my M3 tomorrow night

and as ive got a kid on the way i wanted more of a family car so ive decided on a focus st, i dunno wether to go for a 5dr or 3dr tho.
Wots the bad points to look out on them and wot are they like on fuel etc
Would it be best to buy a modified one or a standard one?
Got around 8k to play with and i am tempted by a RS focus aswell lol
Any help would be great thanks
