Used cars up to 5000 Euro

Good evening, I have been reading in the forum for some time and have now signed up because I am looking for a car. I need the car especially for my way to work (20 kilometers and 20 kilometers back). It is important to me that the car is reliable and the maintenance costs are relatively low. My budget is 5000 euros, but I would also be willing to invest a little more money (up to 7500 euros) so that I can keep the car safe for the next 4-5 years without big problems. By reading in the forum I have already taken an approximate picture and would like to ask you about it. Toyota Aygo Coolhttp://suchen.mobile.de/…/194431296.html?… Ford Focus 1.6http://suchen.mobile.de/…/1943956606.html?… Ford Ka 1.2 http://suchen.mobile.de/…/195014214.html?… Or would it make sense to increase some more money in your hands and invest in such an Opel Corsa? Opel Corsa D 1.2http://suchen.mobile.de/…/191788178.html?… Would you really be great if you could use a little more space to get into a Opel Corsa? I can help. Greetings
