Final answer:
The benefit of 2021 NV200's rear windows with privacy glass includes increased privacy and security, reduced UV exposure and heat buildup, and improved aesthetic appeal of the vehicle.
Step-by-step explanation:
The benefit of the 2021 NV200's available rear windows with privacy glass is primarily the increased privacy and security offered to the contents inside the vehicle. Privacy glass, also known as tinted glass, helps to limit the visibility into the vehicle from the outside, which is beneficial for businesses that use the NV200 for transporting valuable goods or sensitive information. Furthermore, the privacy glass can filter out UV rays and reduce heat buildup within the vehicle, creating a more comfortable environment for passengers and goods. Finally, the aesthetic appeal of privacy glass can also be seen as a benefit, as it gives the vehicle a more polished and professional appearance.
