Compact car (5-door) for the city with automatic and inexpensive maintenance

Hello dear community, I have spent the last 8h reading all kinds of threads here in the forum, but now I think that I need my own… I am looking for a compact car with 5 doors by the end of January at the latest. This is mainly to be used in the city, I estimate the annual driving performance at only about 3000km, because it is really mainly used in urban traffic. I have about 4000-5000 euros available, my highest maximum is 6000 Euro, whereby I would prefer 4000 Euro of course… As far as manufacturers/brands are concerned, I am quite emotionless, much more important to me that he meets my requirements: – 5-door – enough large interior for the driver (although slim, but 1.90m tall) – automatic – air conditioning – cheap monthly fixed costs (tax and insurance) – as reliable and low maintenance (who doesn’t want that ) It is best then to make a kl a little something, should not look like most 90’s cars… Due to my application profile I assume that a petrol engine would be the most useful. I would like to drive the car for a few years without much stress, which is after that, is for me currently rather secondary. It is indeed my first own car (by the end of 20), but I am still not a driver, had so far only no own car and know me accordingly little with I am looking forward to your specific tips, by the way, I am looking primarily for the area Baden-Württemberg, Rhineland-Palatinate and even Hesse with cuts. Thank you very much for your help!
