I live in the United States, am around 22 years of age, and recently graduated college with around $12,000 in student loans. I have had a full time job for around 4 months that pays around $55,000 a year and I live my parents so my living expenses are low.
My car is starting to become unreliable with it just passing 200k miles on it.
I'm looking to buy a car around $20,000 - $25,000. My credit score is a little below average (I think around 670), and I have very little credit history. Never had a credit card, or any bills to pay.
I'm starting to apply for car loans, but I'm noticing that I keep getting rejected for a loan of $15,000 because I have no credit history.
How do I improve my credit fast so I can get approved for a car loan and not deal with the headache of an unreliable car?
The only way I can think of is it start paying my student loans now even though I am still in grace period, but will paying them in the grace period improve my credit score since they are not technically due yet?
Should I open a line of credit?
It's currently the end of October and I would like to get that car around late December.
