With interest rates this low, I would be thinking about buying a house or at least saving up for a deposit. Wait a few years then use equity to buy yourself a newish car or another property.
I know you dont work full time so you may struggle to get a house loan but buying a pricey car when you are still on minimum wage is not the best idea.
I borrowed 5 K while working casually and studying, let me say I will not do it again. I paid it back within 11 months but I paid way more than 5 K back to them.
Stay car free if you can, use your mums car. Then once you graduate and get a proper job... go nuts.
Dont look for the easy way, esp when it comes to money. If you bust your balls now, save and invest for the long run, you will reap the benefits later on.
Car debt is bad, home loan debt is good (as long as your property grows in value). Cars depriciate, houses (land content) appreciates.
