What is the most important feature to look for when purchasing an Audi A8?

I am in the market for an Audi A8 and I am overwhelmed by all the different features and options available. What is the one feature that stands out and makes a significant difference in the performance and overall driving experience of the Audi A8?

As a long-time owner of an Audi A8, I highly recommend prioritizing the Quattro all-wheel drive. It provides excellent traction and handling, making it perfect for all weather conditions.

In my experience, the Audi Virtual Cockpit is a must-have feature. It displays all the necessary information right in front of you, allowing for a safer and more convenient driving experience.
