For cars which are older than 10 years, you are advised to make sure the car has a 10 year COE because a car with a 5 year COE which has expired cannot be renewed. After ten years of driving their initially new car, many people just opt to buy another car by trading in the old model rather than trying to get another ten year's useful life out of it, as may well be the case elsewhere. Old cars are often sold off to other countries for parts for this reason and people have suggested that the inner parts are built with a 10 rather than 20 year life in mind, seeing as the owner is likely to get rid of the car in that time.
Road tax is another consideration.
Although smaller, the sum will also always be in the thousands, and once again folks, once your car reaches the magic age of 10, it becomes more expensive. Otherwise one suggestion would be to ask a few car-owning friends or colleagues which insurer they use and get an idea of preference through word of mouth. All of the above should hopefully provide some helpful pointers to those thinking of purchasing a used car in Singapore. Word of mouth is another powerful ally you should explore.
