If I want to, I might be able to double my hours at the card store.  I'm on Monday, Wednesday, and Friday nights right now, 4 PM to 8 or 8:30, depending on the season. 
I might be able to add Tuesday, Thursday, and Saturday nights.  So I'd end up working nights there six times a week, starting in the early afternoon, which might screw up my attempt to make a school schedule (probably will), and may be a problem for doing homework, eating dinner normally, or sleeping.  
On the other hand, that would double my income to some $533/month (over the full year), and I could feasibly bump the car loan payment up to half of that, since there are no obligations on the increase.  So that's $11667.  Which would be a hell of a lot better, and go from not even affording a Mazda 6, to a nice Mazda 6, or even a slightly worn Mazdaspeed3, or a Nissan Altima 3.5 SR.
