Is Refinancing With It

20K miles on a 2020 Accord 2.0T. The total is $34,000, which is 51K for 77 months at 13% APR. The APR will be reduced by around 8% if I refinance through My Union. Is it worthwhile to do it now or to wait a year for higher credit and a lower APR?

This week is the first automobile payment.
