The result of the internet factor is very interesting. The model suggests that a greater number of internet users has a significantly negative effect on the sales of new motor cars. The reduction of new car registration from e-commerce
means that government may lose their tax revenue from the lower sales number of new motor cars. However, this result might be in contrast with our expectation. Because every motor car needs to be registered with the government before use, users must find it quite difficult to smuggle. The growth of the internet should not reduce the number of new motor car sales. Decreasing in new motor car sales from increasing of internet might be from the substitution of second hand car trading via the internet.
