Financing at neg.Schufa?

Hello first! My friend built an accident two months ago and his car was then completely broken and is directly on the scrap yard. So now we need a new car, of course, but can not pay it completely at once. He earns 2400,00 Euro net. But is neg in the creata in it, though already 2 years than done, but can you still finish a car? Shouldn’t be an expensive, a used car. Do you have any idea which car bank does that? Do you have experiences and can you give me advice? Thank you very much! Greetings Blacky
