It can be, but only if you are positive you can hold up your end of the deal.
Taking out an auto loan when you don’t currently have one can improve your credit mix. Your credit mix makes up 10% of your FICO score. Your payment history makes up 35% of your score, so on-time payments can give you a boost.
At the same time, if you make late payments, your credit score will likely take a nosedive. And if you take on a loan when you’ve already got a lot of debt, your credit utilization ratio might go up. This can negatively impact your score.
