My Belvedere is very warped as well. It was really jammed in the box. I wrote to them and even offered to pay the postage. The response I got was, build the model. When you put it all together it should straighten the body out. If it doesn't, let us know and we'll take you up on your offer to pay the postage. That's the jist of it anyway. Like i'm going to go to all the work of prepping, priming, painting a body then assembling it all just to find out - nope it's not going to straighten out.
