The butterfly Mercedes-Benz you mentioned should be an S-class Mercedes-Benz with chassis model 220, which was launched in 2000. This model of car has been discontinued now, so you can only buy used cars. Now all S-class cars with chassis model 22 1 are in 4S stores. We only look at the chassis model when repairing Mercedes-Benz, not the displacement. The price of second-hand cars varies according to the car condition, mileage, violation record, annual review and insurance situation.
