Give him the present of Financial Peace University (FPU), the Ramsey program. It’s $120 or so and he is at PRECISELY the time of life when he needs it. My daughter and future SIL are taking it with us right now.
I’m a JAG and have had more legal assistance sessions than I can count with E-3s through E-6s and O-1s through O-3s that have the same refrain: “I bought this car cuz I could afford the payments. Then I got a credit card cuz I could afford the minimum monthly payment. Then I missed a payment. Now they’ve repossessed the car and the credit card company is hounding me. What do I do?”
Unfortunately, younger people who are for the first time getting a regular paycheck seem to thing they’re rich and/or financially bulletproof. I hope your son sees the light before becoming car poor.
Did I mention FPU?

Thanks for that.
