Suitable car for the country

I’m moving to the country. So far I didn’t have a car of my own, because I lived in a big city and could drive everything with DriveNow or a rental car for longer distances. Otherwise I drove a train. The village has a railway station, but is otherwise about 30 minutes by car from the next big city. There are of course neither DriveNow nor other providers directly there. Therefore I wonder which variants there could be. I will not use the car every day, but to the big buy every three to four days in the next shopping center I need one. In order to “get out”, every 5 days, I also need it. However, usually less than 100km. What kind of contract do you propose and why? Meaning: purchase contract, i.e. buy a new or used car lease contract, etc. With the ulterior motive to find the cheapest offer for my needs. In the car itself I have practically no demands. Small, enough for the mentioned activities.
