Help with car purchase/decision

Hello, I’m still driving a VW Polo 6N2, which needs to be replaced. I drive about 12km to work every day, mainly rural road and in the city. Highway rather rarely. The car should be as economical as possible in maintenance / consumption, reliable, not prone to repair and “stable” / safe. A small “women’s car” that comes into every parking space and does not have all too much PS. My wish would be a touch display with USB and Navi/ mobile phone connection. I’m looking for a well-used car for about 8.000€. Models that would be interesting to me from an optical point of view: -Opel Adam 1.2 Jam (69 hp) -Opel Corsa E Selection 1.2 (69 hp) -Audi A1 1.2 TFSI (86 hp) -Seat Ibiza 1.4 16V (86 hp) Unfortunately, I can only visually evaluate these cars and have no experience with technical things and engines. Maybe someone could help me with the selection? Which car would be the best choice and what do you have “reasonable” g or are there other cars in question? I am totally overwhelmed and grateful for every answer. I thank you already in advance for the answers.
