Explanation
The specification does not clearly define the dependencies between the power unit and the body style options. For example, it is not clear if the user can select a hybrid power unit and then choose a saloon body style, or if the hybrid option is only available after selecting a hatchback body style. Similarly, it is not clear if the user can select an SUV body style and then choose a hybrid power unit, or if the SUV option is only available with petrol or diesel power units. These dependencies affect the usability of the site, as they may confuse the user or limit their choices. The specification should specify the valid combinations of power unit and body style, and how the site will handle invalid or unavailable combinations.
