As of my knowledge cutoff in September 2021, the most expensive Range Rover model available was the Range Rover SV Autobiography, which had a starting price of around $211,000. However, please note that prices for luxury cars can vary over time and depend on various factors such as optional features, customization, and regional variations. It's always a good idea to check with a Range Rover dealership or the official website for the most up-to-date and accurate pricing information.

I apologize for any confusion. As of my knowledge cutoff in September 2021, the Range Rover SV Autobiography was the range-topping model in the Range Rover lineup. However, it's possible that newer, more expensive models have been released since then. Please note that pricing for luxury cars can change over time and can vary based on options and configurations.

To get the most accurate and up-to-date information on the most expensive Range Rover model currently available, I recommend visiting the official Range Rover website or contacting a Range Rover dealership directly. They will be able to provide you with the latest pricing details and any new models or special editions that have been introduced since my knowledge cutoff.
