Owning a car in Singapore is expensive .Surchages levied on buyers to discourage peak-hour congestion cost more than the car itself.They include a 45% import duty and a 150% additional registration fee. Annual road tax is also steep: $390 for a 1000 -cc car.Add on a $565 registration fee and a few thousand for a certificate under the republic 's quota scheme--and by the time a buyer gets behind the wheel of a $10,000 vehicle,he will have paid much more than $30,000
