Or can i get one while on disability? My mom suggested certified used but thinks i should wait until i have a job. I could reasonably afford the estimated payments on the car I decided on. I know that I will get a job eventually. But the breaks went out on my current car and though it happened in a parking lot and is being repaired. It's just not trustworthy any longer. I would trade it in after talking to my brother. Should i do it or wait?
