Auto Loans

Do auto loans hurt or help your credit?
I recently purchased a vehicle, on my credit report they saw my tv that is financed and it apparently dropped my credit quite a bit (under 700), it comes off as an unpaid credit card even though it was part of a promotion.. Anyways, I got that loan, but i’m curious if this auto loan will further harm my credit?
I wouldn’t pay it off for 6 years based on the plan I got in, but i’d make the payments on time every month.
Depends if you pay them off or not…
