Attention in this upgrade was also applied to comfort with the passenger cabin widened by 50 mm (2.0 in) and larger seats. The luggage compartment at the back finally became accessible from outside, using a boot/trunk lid and ventilation was improved. To differentiate them from the existing models, the petrol/gasoline and diesel versions of the upgraded cars were designated internally as the Mercedes-Benz 170 Va and Mercedes-Benz 170 Da.
