I would rate the ride quality of my 190e2.6 as firm, but compliant.

the 201 naturally does not smother bumps as well as a 124, due to its lower mass (i.e., inertia). High-frequency bumps like tar strips are felt at high speeds and cause some vibration to be transmitted to the cabin.

like all benzes however, the suspension has the ability to swallow large bumps, due to its long-travel articulation.

the shocks as well seem firm at low speeds, but adapt at highway speeds to soak up major bumps, giving the car a sense of stability and poise at all speeds.

the firmness of the seats are in tune with that of the suspension, which gives the driver/passengers a feeling of solidity and stability.

the result is that, for a relatively small car in the 201, you get an excellent long-distance cruiser.
