That was pretty obvious (that it had been prepared), you can see how plenty of the parts are just popped on/in and not bolted on, but that does not change the fact that it drives in and drives out and is disassembled in to it's main sub-assemblies in a ridiculously short time.

If they did the same thing having to drain fluids and so on it would likely be a lot more messy, and more risky (and a bit slower) so I can see why they didn't choose to do it that way.
