My wifes's car loans is in year two of a 6 year not and my jeep note is in the first year of a 5 year note.
So you went from owing $0 to about $35k in a little over a year?
I'm not knocking you making decisions on what you feel is best, but your budget appears to be stretched pretty thin. I would do the snowball on the CC, then the SL, then the cars. You should be full on Baby Step 2 for 3 to 5 years. That's a long time. And by the time you get done - those cars will be looking pretty "old" again.
Those cars just cost millions - I know whereof I speak. I did the whole "Let's buy a bunch of cars" thing - it did not end well. I do carry a loan on the wife's truck, but I had enough in Baby Step 3 to have paid for it. I am "borrowing" the money from myself in that case. It does not sound like you have much of an emergency fund, either, but I hope I'm wrong about that.
Anyway, good luck with it. I've increased my net worth by over $60k in 4 years following Ramsay's principles, generally. I kept my retirement contribution enough to get the match and I borrowed money for cars (one at a time, of course), but then those became my Baby Step 2 until resolved - I've worked about 1000 hours of overtime over that period, and only taken 1 family vacation. I only buy used cars and I drive them until they cannot be driven any longer.
