Q: Cheap credit from 3.71%

Hello Kolleschen, I always see these super cheap credit offers with 3,71 or in some cases even more favourable for financing consumer goods. But how for heaven’s sake can I get access to such dreamy conditions. Sure in times of Basel II one will certainly have to show a good “bonance”. But could someone tell me exactly what one would have to prove for such a loan with a low interest rate?
