"The 180-190 and 220-220 S 'Ponton' models looked very similar in appearance from the windscreen back to the six-cylinder somewhat longer 220s-220 S-220 SE models. From behind, one could not easily differentiate even the top of the line 220 SE from a 180 but for the longer bonnet and chrome touches. The 180-190 four-cylinders were widely used as German taxis. Only these shorter Pontons featured low-wattage parking clearance lights at front and rear bumper. A simple left-right toggle above and to the left of the driver's knee selected which side would illuminate so as not to needlessly run down the battery in winter. Heater air intakes were on both sides of the radiator grille only on the 120/121. 
This left hand drive 190D Ponton was imported into the UK in 1989 and has been in the hands of the vendor for the last 19 years. We are advised the car needs a light restoration and the brakes need attention although we are advised the engine runs well. Finished in white, this Mercedes-Benz Ponton is an ideal project for a competent DIY mechanic."
