That's a good point of concern. I believe the Ponton in the link had both the front and rear subframes grafted from the 201 chassis. The 201 was the first truly modern MB chassis, and all the newer passenger vehicles they make share very similar suspensions; some producing over 500hp.
I should also draw attention to the rather short and narrow engine bay in the early four cylinder Pontons, which makes them poor candidates for vee configured engines or an inline beyond five pistons.
