You can own a car, regardless of how much your pay is.
But, how long you can keep the car with you is 1 thing.
As long as you can pay your first instalment, road tax and
insurance, down-payment upfront after you signed on the dotted
line, the car is yours !
At the most in the future cannot sustain,
No $$ for instalments : bank repossess car.
No $$ for road tax / insurance: LTA repossess car
No $$ for parking fine: HDB / URA charge you in court
No $$ for traffic offence: TP charge you in court (May lose
licence and + demerit points)
At least, you can proudly say that "I HAVE OWNED A CAR BEFORE
!!"
