First car with 18 years… maintenance costs !!!

Hi guys, I’m looking for my first car. However, I’ve come across a couple of questions that no one can really answer in my environment. I’m already looking for Mobile.de and Autoscout24. And if I make an insurance comparison for a Golf 3 with 75 HP, contributions like 2000€ annually or 178€ monthly come out. How should an apprentice with a net salary of 560€ + fuel, tax and registration can afford such a thing? I have 140€ Saved and wanted to cover the remaining 400 for fuel, tax and registration. Do you think that works ?
