Truck Buying SItuation..Advice Please

[semperfidoordie]

Here's my situation...want some advice

I'm in the Marine Corps..21..have 2 years left in...getting back from Iraq in July...paid off all my bills except my car which I owe 7300 on...will be able to save a lil short of that before I get back...car payments aren't bad...223 a month...wife is getting her license soon and is a full time student with a part time job...she wants the car which is fine by me but I want a truck so we have two cars cause both of us driving one just doesn't work...found my dream truck for 6500 bucks...i'll have that when I get back...should I buy it and have little in savings? Or should I pay almost all the car off and have nothing in savings? Or what else should I do? i'm in a awkward situation as she doesn't care she's happy with anything but I really want this truck...well honestly i want a truck preferably older and reliable with no car payments..help!
