I helped a pal load one in a Pope mobile for a trip to France (his home) last year and we did the same. Removed blade, seats down, bandsaw on its back and then loads of straps and bungies holding it down inside the vehicle. I recall we wedged it in various places too to prevent any risk of it rolling at all. It was a mid sized Scheppach, don't recall the model.
His car was good in the sense it had a number of strong steel loops attached to the frame which were designed for strapping wayward loads to.
