Yes, the 201 cars were the first Mercedes to use this technology. All the following cars 124s, 140s, 202s, 210s, etc. use that same type of dampening. The earlier cars had separate engine shocks that added parts and assembly complication. These mounts start to fail around 80 to 90K. The symptoms are feeling engine vibration in the seat or steering wheel. A new set goes a long way to restoring that new car feel.
