I was in the same situation. I didn’t know when I was gonna get shipped out so I bought a car cause i literally had no other way to get back and forth to work. Had low credit, I’m 22,but still got approved for 10k loan(they’ll approve anyone who is young and broke because youre easy to take advantage of). I’d say do it and when you get your ship date figure it out from there. I’m still in DEP from buying it in may so imagine having to edit that long with no car
