One of the best ways to improve your credit score is by financing a vehicle. This might seem a little counter intuitive, but over a third of your credit score is made from your payment history. This means with every payment you successfully make your credit score will increase. If you keep making your payments on time and in full, you will start to see a dramatic increase in your credit score.
At the end of the day, even if you have bad credit or no credit you may be able to qualify for a vehicle loan. Even though it might be at a higher interest rate, the increase in your credit score is worth it.
