We signed a loan contract in postbank and everything looked OK and there were no things to worry according to the manager. I already had the car in mind which I wanted to purchase, but 1 week later the rejection came without any explanation. We spent 2 hours talking to the manager, payed 3 euro for parking, and there was no positive result after all. My latest shufa rating is 97% (maybe was after this rejection) and my income is more than sufficient to pay this loan back.
