low maintenance and affordable student car ~350€

Hello! I’m looking for a solid small/compact car for about 350€. As a student you’re not Krösus, so the running costs should be low and workshop stays rare. The most important criteria I have are: – 5 doors (I will often go somewhere with friends and don’t really feel like the theater with the seats) – petrolers – low fuel consumption – more than the usual 60 hp (with 4 man and a box of beer he should already A nice feature would be an AUX connection, because I definitely want to play music via my mobile phone, but I can also retrofit a new radio, which, however, also goes back into the money.. I have meanwhile been stuck on the following cars, but have no idea if this is really the optimal one. That’s why I’m also open to alternative cars: – Golf 4 – Opel Corsa c – Opel Astra h I have no idea at all which engine or what kind of equipment is good, but that’s why I ask here too. I hope you can help me. Thank you very much in advance!
