Final answer:
In a showing report, the type of car the buyers were driving is not relevant and does not need to be included. The focus should be on buyer behavior and interest in the property.
Step-by-step explanation:
In a showing report for a property sale, it is not necessary to include what type of car the buyers were driving. While details such as, 'What questions the buyers asked' provide insight into what the buyers are thinking, 'If the buyers stayed longer or shorter than normal' offers clues about their interest level, and 'If the buyers sounded excited' can indicate their enthusiasm towards the property, the type of car the buyers came in is generally irrelevant to their behavior and interest in the property. This information does not contribute to understanding the potential for a sale or the buyer's motives and preferences regarding the property.
