First car for ~15000€

So, hello to everyone, because this is my first post here and I hope that I have taken the right subforum. On the topic: I now have my driver’s license in my pocket and am now looking for my first car. To this I would like to say that I would like to buy a new car or an annual car with a few kilometers. Therefore a small car would probably be the right choice. What can you recommend me there? Of course he should consume little. On special equipment I do not put sooo much worth, but a little bit of comfort (air conditioning system, electric window lift in front etc.) should already be in it. Thank you already for your answers!
