Actually its the other way around if you talk about A4 and A6. I hardly see any C class mercs and have started seeing more new A4 and A6 instead. And probably because if the pricing strategy Audi has taken for Pakistan which is due to the smaller engines they have resulting in less duty.
The new A6 and A4, 2 cars combined are about equal to the price of one new E class. Atleast in Lahore Audi can be seen much more than new Mercs. Talking about A4 and A6, when ot comes to S class, that is more than A8
