No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Sounds like you really want a Jeep but NEED a car.
Do you need your husbands income to qualify? If not and he has really bad credit apply yourself.
Spend a few bucks get your and your husbands actual FICO scores. Post that information with your individual and combined incomes and DTI ratios and we can probably help. Short of having that information there really isn't anything to go by to provide a suggestion. Generally most need the income of both spouses and as long as one has good credit the deal can get done. I always suggest the main credit unions here DCU, Penfed and NFCU for preapprovals before you go shopping for a car.
I think you'll be fine. Since your already with Penfed that is who I would work with.
