Just pay the loan off now. It will feel like a big financial hit, but it will be cheaper than continuing to make payments with interest accruing.
In the future, be advised that it only makes sense to debt finance a non-revenue producing asset if the interest on the loan is lower than the return you can reasonably expect to earn by keeping your money wherever it is currently parked. If I have my money parked in a brokerage account and I conservatively can reasonably expect 7% returns and I can get a car loan for 3%, I'm taking that loan because the cost of borrowing is less than the earnings I expect by leaving my money invested. If I have my money in a savings account earning 1% and my car loan is 7%, I'm just going to pay cash because the cost of borrowing is way higher than the interest I'm losing by pulling cash out of the account.
