Need Help!!

Okay I have $1,789 saved I'm turning 18 on September 24th and I have to move and I also need a car 😫 I've went to a police car auction and saw a lot of cheap cars that needed little work spoke to a few people as well. I found a car for $600 its a dent in the back door nd just needs more brakes. I also have to move by October 1st. What do you think I should do? Help please nothing rude

Update: My Bf works in a car shop so I'm not really worried about the car needing fixing 😊

Also I only have 2 sisters they are both in college I lost my mother at 15 and have no relationship with my father I'm currently with a friend of mine but she's moving October 1st & My bf is also helping with getting an apartment I forgot to add that very important part 😁
