Singapore used car from a dealer: does Lemon Law cover second-hand cars?

Yes. Singapore’s Lemon Law applies to second-hand goods, including second-hand motor vehicles bought from a business. What counts as satisfactory quality takes account of factors such as the vehicle’s age, mileage and price. Consumer-to-consumer private sales are not covered by the Lemon Law.
