Enlisting in Army with Voluntary Repo in collections..

Hey guys. I'm planning on enlisting but was researching all I could before I finish college on requirements to enlist. I currently have a voluntary repossession of a vehicle from earlier this year that was sent to collections (9k owed after auction) and it shot my credit down to 550. I haven't made a payment plan yet but plan to. I am curious when I meet with a recruiter by the end of the year if they will work with me. Also, if security clearance plays a factor if I am showing I am proactive in a payment plan. Thanks for any help.
