20-year-old beginners looking for cheap first cars

Moin all together, I finally pulled it through and did my driver’s license with a bit of delay (20 years). Now that I’m on the road quite a bit, I’m looking for a suitable car for me. Because I don’t have too much idea of cars or possible models, I hope here for support and experiences or tips from you. ____ So so far I can’t say anything about what and what the vehicle looks like or what it looks like from the performance, from Since I live in Hanover it should be able to take off the city traffic and for this reason perhaps not too much in the consumption costs because I am still a trainee. (at least daily driving kilometers 25km). Besides, the insurance will certainly be higher, because I made my driving license only at 20 years. So so far: -Max. 250€ -not too big, not too small, -air conditioning -Radio -possibly very low consumption -Enjoy me in the insurance via tips, suggestion ags, etc.
