'92 Baron vert...rust???

I'm looking into a '92 Lebaron vert w/ 130K. I haven't had the doors open yet, they are needing replaced (pretty rusty across the length of the bottoms)...the top is fairly new. I can only assume that the old roof must have leaked given to the rust on the doors because the rockers & the rest of the exterior looks very clean, no salt damage.

My question is when these leak, where are the common areas on the floors where I should be looking for rust damage? Trunk? Inner rear wheel wells? The well for the top? Driver/passenger areas?

Any help is appreciated, I intend on looking at it this week sometime...I've found a really good deal on a pair of doors, it also needs tires, exhaust & the hood latch is either damaged or the cable is hung-up. So a wee bit of reconditioning is in order, but I'd rather not if it has bad cancer. They did tell me on the phone that everything does work on it & it runs well. We'll see.:dunno:

Thanks in advance :thumbsup:
