Car possibilities

Hello, my name is Alyssa and I am trying to raise money to get myself a car. I bought my first car about a year ago and it currently has 240xxx on the odometer. I'm worried driving my car on my daily commute of 30 miles each way. I work 6 days a week and take on all the extra work that I can but I just can't seem to get over the hump I'm in. I've been trying to save, but unforeseen incidents have docked my savings quite a bit. And I feel that my car won't last until I will be able to save the amount that I need. Anything helps. Thank you for the consideration, have a wonderful day!
