Is funding worth it?

Good evening, I would have a question about the financing. I am currently 17 and trainee in the second year of my apprenticeship. From this month I get 730 Euro net from my employer. Since next July I will be 18 years old and therefore I can drive independently (currently still Bf17) I wanted to ask myself about the topic car. I had to run a financing about my mother (she has a secure income) with 3000 Euro payment from next year July (I have to go to work with a car from then on, as the road is very cumbersome with public transport at the moment.). As a car I imagined a BMW that was best driven under 100,000 km and lasts long. The rates should then be about 200 euros from July until the 6 000 euros have been paid off. I know that it is already high demands but that must be theoretically possible. Now my question is whether it is worth a car with finance (Small information on the edge: My work path would be 25km back and 25km back and that from Monday to Friday in one month (= 50km x 20 days = 1000km a month + still private driving by car)) Can someone give me a tip on how best to solve it?
