The trade off is the number of passengers the consumer could haul in the vehicle and make the decision based on that or the fuel efficiency rating between the two vehicles. A sports car would consume less fuel because the vehicle would not be weighed down with the extra passengers than a family car but a sports model may have a high performance engine which needs special maintenance or premium gas.

The second force in decision making by the consumer is the price or cost of the goods or services. Price plays a crucial role in the decision making process because it determines how much can be afforded to make that purchase and the value the consumer realizes from purchasing at a certain price. It is not only the price of something that drives the decision to buy a sedan or a sports vehicle a consumer should consider the
