Make it 29 instead of 30 months remaining, or even possibly 28 if CA DMV stalls.
Are additional miles 30 or 25 cents on the iX? Regardless, you can prepay at a small discount either now (and possibly include in future payments) or do it up until 1 day prior to maturity.
@Markszachary54 post a picture of the sticker or build sheet and people will get their answers re DAPP, etc from there.
