I've seen this approach used successfully a number of times on motors whose crankshaft bolts were torqued in the 100-150 lb. range.
I forget the exact torque figure for the MB 27mm crankshaft bolt, but it's somewhere upwards of 300 lbs. on the 126 cars, be it 103 or 116/117.
In this situation, I'd bet a buck that the "bump starter" approach would snap the socket-connection end of a lesser-quality breaker bar right off. I wouldn't chance my high $$$ Snap-On using the bump starter technique. In a few cases, people have mistakenly set the breaker bar the wrong way and ended up tightening the crankshaft bolt, breaking it off. Stuff happens.
I've also seen the "bump starter" approach wreck expensive inerts when the breaker bar got loose and went sailing.
I'm sure others have employed hill-billy strategies that worked. Getting it off is one thing; getting it back on and torqued to spec is something else.
I'd buy the flywheel lock, but that's just my opinion.
