I recently bought a v reg bmw 323i , When i was driving it last night the steering totaly went on it, the steering wheel was making a very loud noise and was shaking badly, now i am unable to drive it at all, does anyone have any ideas what could be wrong with it....PLEASE HELP

Do you still have front wheels? If not, that is probably the issue. Otherwise, its the steering rack. So, uh, GL on getting it fixed cuz it wont be cheap or easy.
