The cost-performance ratio of a car mainly refers to the ratio of performance to price. Although there is no fixed formula for calculation, it is nevertheless an important purchasing criterion valued by all consumers. Nowadays, under the fierce indoctrination of car manufacturers, most potential car owners' concept of cost-effectiveness has become simplified into a mere comparison of configuration-to-price ratios. In their eyes, for cars of the same price, whichever looks better and has more configurations is considered the better choice.
