Same construction method, most softies are based on car platforms (floorpans) anyway. (Kluger = Camry, Territory = Falcon, BMW X* = passenger models, RAV4 = Corolla, CRX = Integra, Tuscon/New Sportage = Elantra, etc.). They may be modified for use with rear diffs, etc., but they do not have any "stringers" holding them together along the floorpan, relying almost soley on the transverse welds in the floorpan for strength. Once these welds start to let go, they unzip like a zipper (seen in the video). A full chassis vehicle (or chassis in body vehicle) has the (obvious) chassis from front to back with adequate strength and support of the body to maintain structural integrity.
The floorpan of a vehicle is one of the most expensive parts of the vehicle to engineer, due to the contribution it makes to strength, suspension/handling, physical location of components, and load carrying. Everything else in the superstructure by it's nature is "windowdressing" in comparison. Reusing the floorpans (even with modifications) with new superstructures on them is a far cheaper way of designing a "new" vehicle than actually designing a floorpan from scratch for every model.
The main differnce in recent times has been the crumple zones leading to weaker ends of the vehicle to absorb the energy of an impact. There simply is nowhere to attatch a decent
anchorage point as it's all designed to "fall to bits".
