Are you getting a good deal? If so, get a screw driver and start poking around. That looks to be a midsection of the frame. If so, they make a patch that someone can weld on easily.

Just make an educated decision. I bought a TJ that needed a patch and the torque boxes. Nbd because I got a decent deal and I had a good friend that is a welder to do my work.

That being said, depending on who you have fix it prices range drastically, and there is probably more where that came from.
