Are you AF? I'm asking cause I am and I did the Korea thing.....and I left two cars in the states for the year I was there. I think USAA may offer quite a bit lower insurance if you are overseas and your car is in storage? But then again, maybe you'd have someone driving it while you're gone?
Either way, I agree you should wait. You never know if your mind will change during that time. And it gives you something to do while you're over there (besides drinking cause that's all there is to do
). You can search and do a ton of research and be sure what you want to buy when you get back.....
