Is Toyota Belta a good car and good to invest in? It shares the Vitz underpinnings, including the drivetrain and platform. This vehicle is well-known for its dependability and safety ratings, giving it an excellent value for money. Toyota Belta fuel is efficient. It starts at 20.04 and goes up to 20.65 kmpl. The petrol mileage for Toyota Belta ranges between 20.04 kmpl - 20.65 kmpl. Someone wants to invest his money in buying a Toyota Belta but I told him to asses the var because a car depreciates and never appreciates, so I told him to ask the age and the driver.
