Yesterday I went to inquire about Suzuki Ciaz from Zeeshan Autos (Suzuki Authorized Dealer), Hyderabad. He said that as there is no with holding tax on this car's invoice price its registration includes extra fees of Rs. 100000/- approx. He told me that if you are a filer you will have to pay 100000 for Registration else registration fee will be around 150000.
I searched in on road price calculator and registration fee is normal and same for all 1300cc to 1500cc cars, which makes much more sense to me.
