20% of income would be an acceptable level to maintaining a car

20% of my monthly income is what I’ll feel comfortable spending on a car. It contains the car mortgage, petrol, road tax, erp, parking, etc. If only for operating expenses, 10% of my income would be acceptable.

What's more, share a advice I received before is that your car cost (COE + buying the car) should not exceed your annual income. Typically, car expenses in Singapore would be no less than 1.5k a month. To keep some buffer, you may need to save 2k a month for a car. So to take home at least 10k a month would be a suitable level for becoming a car owner?

It seems that looking at second hand cars only would be a good choice?
