I want to say for Cars in Singapore, it is probably more accurate to include the car depreciation in the monthly expenses. A normal car here already depreciates at about $12K per year or $1K a month, and that is assuming you use the car till the end of life. If you are the type that change your car every few years, the depreciation is probably higher.

Then add in petrol, insurance, road tax, parking, ERP, servicing, grooming, repairs etc. The real number rises quickly to $2K or even more if you have a conti/luxury car.

Cars damn expensive in Singapore man
