No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I'd personally re-establish the emergency savings while you payoff the credit card debt. It will take a little longer and cost more in interest, but savings is key to avoiding financial catastrophes in the future.
I also wouldn't remotely consider buying a new vehicle until that savings is already established.
By the looks of our plan we'll have replinished roughly $5700 in savings by end of March.
