When you compare with civic.
1-When it comes to size it is smaller then civic in length and width is same as civic.
2- Interior and exterior wise way way better then civic and also has many more functions then civic.
3- seating capacity and leg room is more then civic.
4-performance and handling much beter then civic.
5- vezel being an suv has much better road clearance then civic which i think is very important on the roads of karachi.
6-build quality we all know that pkdm can't match with jdm.
7-much better fuel economy. Vezel being a hybrid is giving arround 15-20kmpl and civic will give you arround 7-10kmpl max.
So overall vezel is a winner in all the cases as compared to civic and is 100% recomended.
But the con that i see in vezel as compared to civic is that vezel is 0.7million expensive then civic and mantainence is dificult and expensive. But in near future there will be a lot of vezels on the roads even more then prius. So mantainence problem would be solved soon.
