I agree with scareface on both things... bootcamp + Letters = AWESOME... letters in bootcamp, or a package on deployment would totally make my week. you could kick me in the nuts on deployment, but if i had recieved a package from the wife, or parentals, i would be ok with it...
as for the car... the military doesn't pay much man, not much at all... not till you hit E4+ even then it's not great,if you're car is paid for, keep it. bank all that extra money... a car payment while you're in the military sucks, cause it takes away that extra bit of cash you want to use to hang out with your buddies, or buy the clothes, or get a hotel and get wasted on the weekends. LOL... I wish i would have had a car when i got here. i bought one while i was here, and it's almost $200 a month i'm out. keep the car, tinker with it. save... did you get an enlistment bonus? what branch did you sign up with?
