Diesel or petrol with MEINEM driving profile

Moin, since in the middle of next year the purchase of another car is due (my car is supposed to get my son), and I like to think and plan a little longer, I make myself a little smart now. The first consideration: diesel or petrol. Electric is still too expensive for me, gas would be an option, hybrid I don’t know. So: I drive about 28 TKM a year, mostly rural road. Highway rare, city traffic also. Rural area, driving ban no topic. Way to work (simple distance) good 5 0 km, rural road with a few village passes and a small town. Hilly area/Harzvorland (South Lower Saxony/North Thuringia). Hardly short distances (with a short distance with me at least 8-10 km (simple distance) are. Driving style: relaxed glider; need no highway hunter, but likes to have torque or pass without noisy high speeds. It is to be a compact car, possibly also middle class (i.e. golf or passat size). Targeted budget approx. 6000 € (financed). in ABM, nothing from the VW group (nothing against the cars, I’m only too expensive), no Dacia (I don’t like it). Couldn’t it be enough for a Euro5 diesel? With the petrol companies, I have no aversion to charged engines / downsize engines (on the contrary, the Focus Mk3 with the 1.0 Ecoboost – petrol would be very appealing to me). It depends on the total cost, which is more economical. “Dark” are both types of engines, but I don’t want to save the world. Community does not go (no colleagues nearby, moreover irregular working hours), public transport does not go (unfortunately outside the next big city arg mau), also no move (house, and my wife works exactly in the opposite direction).
