I have yet to see an actual scaled weight of either 190 or C-coupe here is the states. Because of the options for each country differs so do the weights.

I've seen 3280 lbs for the US C-coupe which might include the Panoramic glass roof. The roof is rumored to weigh 40-150 extra lbs. which would put in the low 3100's. Some say late model MB were quoted with full tank of gasoline and maximum luggage.

The US 190 weighs in the mid 3000's. Not sure how they are contented.
