Good news, I can recommend financing sources that can pretty much work for anyone with any credit score in case you aren’t sure where to go, I’ve made it easy for you.
(listed below so you can choose the best one for your needs)
Financing works like any used JDM dealer or if you were to buy from me with a private party deal: You directly apply with any company you want, my recommendations below, and once approved you have the disposable income to use. Used Japanese dealers, or private party sales, are not “Buy Here Pay Here” and there is no in-house financing.
