I'm with Dan, SAVE. Get your credit cleaned up some more, get a beater to get you around and in a year or two re-evaluate your situation. My husband and I still keep our 90 beater Eclispe around (glad we did after these Hurricanes), to drive around in.
FYI, my car is thru my company, I have a 3 year note at $535 per month. You do the math on what I may have put down. I got an excellent deal (paid well below dealer invoice) off the sticker for an 04 because my dealer was not moving them and wanted to get them off the lot before new ones came in (that still are not moving). I am paying just under 5% interest thru DMC's Business division.
