From that buy guide, it sounds as if the chassis and bulkhead can corrode away, leaving a stack of body panels.
From the images on your search, rust bleeds from the bulkhead through the front of the driver/front passenger doors.
The wheels and the roof rack are going to be sites of rust, and where the spare and the latter are attached
I know what aluminium corrosion looks like, not sure how not to make it look like bird poo on the model.
