Used cars up to 5500 Euro

Hello, I am looking for a used car up to 5500 Euro. It is important to me that the car is reliable and the repair costs are not too high, also the car should have the highest 100000Km down. The maintenance costs should also move within the frame. What do you think of this offer and what should I pay attention to ?http://ww3.autoscout24.de/classified/269191950?asrc=pl的as&testvariant=list3tiers&tierlayer=pl Greetings
