Looking for a reliable car- Civic, Almera, Colt, 323???

Hello! I am new here and since there seem to be many professionals here, I would like to ask you for your opinion. I would like to buy a used car (rather small car, price frame about 2000 euro) soon. But the reliability is most important to me, because I do not want to spend money on permanent repairs. I have the following models in mind so far: Mitsubishi Colt Nissan Almera Honda Civic Mazda 323P What do you think is the best choice? And which criterion is your opinion nac h most important? Model, year of construction or km- speaking on what should I consider as 1. in comparison? I am grateful for every advice!
