Which of the following is NOT a reason for ensuring regular vehicle maintenance?

Guaranteeing zero maintenance costs is not a realistic or achievable reason for ensuring regular vehicle maintenance. Regular maintenance, such as oil changes, tire rotations, and brake inspections, inherently incurs some costs. While these expenses can be minimized with consistent care, the notion of zero maintenance costs is misleading and impractical.

On the other hand, the other options are valid benefits of maintaining a vehicle. Reducing atmospheric pollution is important, as well-maintained vehicles tend to operate more efficiently and produce fewer emissions. Maintaining vehicle resale value is significant because a well-maintained car is often more desirable to buyers, which can lead to a better return when selling. Increased driving comfort is another valid reason; routine maintenance ensures that all systems function correctly, providing a smoother and safer driving experience. Overall, focusing on these positive outcomes highlights the importance of regular vehicle care, while the idea of zero costs is unrealistic in the context of vehicle maintenance.
