i didnt read any ones else advice so take this for what its worth...you are in the military, if you are E-3 or below and living in the barracks wait and get something cheap and used until you hit E-4...if you are already E-4 (and not married or with kids or a house), finance outright and use the 8,000 you've saved to make the car yours...its cheaper to spend an extra 20-30 a month on car payment than it is to save that 20-30 a month to get parts you want NOW...i have had to sit down with way too many newly enlisted kids (not saying you are one) and go over financial plans with them because they overbought. just my .02cents
Edit: and i may or may not have been where you are 12 years ago so i do understand
