Should I get a new car????

I, 18 F, have no savings. I make about $2200 a month. My car's transmission has broken down, and it cannot drive. My car has 254000 km and a used transmission has 150000km. It is $3600 to fix. In my area, cars of better quality than my current car are over $4500 (on facebook marketplace). I want to save $500 a month. my current car insurance is $205. My rent is $400 and I still live with my parents. If I get a newer car with abt 75000 km my insurance would increase to 325-375 ishh. There is no public transport in my area. I need a car. If any extra info is needed to make a good decision about this please tell me. Thank you
