MB, BMW and AUDI duties are not fixed they are cleared according to Manufacturing Model, Package, Options and Optional Accessory. Dont know the duty on C300 but iam just giving u an exmaple 2008 C200 ELEGANCE duty was around 18lacks and 2008 C200 AVANTGRADE duty was 19,50,000/- and same 2008 C200 AMG Package duty was 21,00,000/- and same 2008 C200 AMG PACKAGE but with PANAROMIC Roof duty will be 22,00,000/- so these cars are cleared in Pakistan according to ITP Basis means Import Trade Price and according to Custom assessed value duty would be 204.00 percent. I advise you to wait for a while and when Government revised the age limit of cars to 5 year then import MB,BMW or AUDI. Right now we can only import 03 year old car and 5 year old SUV/JEEP
