Motor vehicle for 2000-300€

Hi, I’m looking for a new car. I live in Hanover and study in Clausthal. So far I drive a Citroen C2 1.1 from 2006. The car has reached 160000km, has always provided me (for a Frenchman) amazingly good services and should be exchanged only because of its performance and size. So I regularly drive home every weekend and driving the highway is simply a pain with the small engine :/ More than a passenger or luggage to carry In the city the car would be great, for longer distances unfortunately it is not so good and I have to be honest with his little fear that the car will leave me in the desert soon.. yet everything is great but you know the shortcomings at Citroen.. I have already made a few thoughts and now need your opinion about my ideas and which cars you would suggest. Price frames would be 2000-30000€ the cheaper the better of course. I think for a short time and for the rest – Diesel/petrol (what is more worthwhile? am so far more with diesel because of consumption and price, but insurance is probably expensive) – >2L displacement (relaxed on the train and in the mountains) – consumption real under 8L (the C2 makes 6,7L at 140kmh ) – top speed > 180, wants to also flow and overtake – combi if possible – reliability – beautiful interior (more important to me than from the outside) – ABS and ESP – would be desirable all-wheel (in the resin lies ha It’s a lot of snow) – cheap insurance (a few values would be nice I don’t really have a picture of how high it will be) – would like to have an automatic car but don’t have to be – if we are already at comfort then a cruise control would certainly not be bad So, so far I see myself at nem Audi, which is quite common as 2.0 and 2.5 and actually fits into all criteria. Only the good and like times 250-300,000km running performance :O pays off a purchase there still or gives the What do I have to pay attention to when buying used cars? Up to what mileage would you buy a car? Which brands do you combine with reliability (Citroen certainly not :P)? And what can I get for the old man? is a C2 1.1 from 2006 and has 150000km down. I thank you for your efforts and your suggestions.
