Trying to finance a car

27/M $2500 monthly Income

Expenses (monthly) :

Rent - $400 Phone-$30 Food- $200 Self Loans - $100

Savings: $8,000

Currently have shit credit because younger dumber me decided to take out 5k worth of loans 7 years ago while I was in the Marine Corps and I never paid it back, the interest eventually ran up to 10k and just this year it was wiped off of my credit report ( which I did not know what a thing )

I have 2 self loans I’ve been paying for the past year and will be completely paid off by next year .

My last 5 federal tax returns have all gone to collections for that debt I’m having trouble getting financed from anybody and if I am offered financing , it’s usually 20+ APR for 5+ years

Can anybody with a brain show me the way, I’m a lot more patient now , I’ve healed myself from all of the impulses and dumb spending habits I used to have in the past . I want to do the right thing and I’m working really hard to prove that to myself but unfortunately , the people with Suites only see what’s on paper :/
