The most relevant data point is the selling price of a similar 2016 Range Rover Autobiography V8 5.0L Supercharged LWB with 161870 km sold for SAR 186000 in September 2023. The car to be estimated has higher mileage at 194600 km, which typically reduces the value. Listed prices for similar cars range from SAR 185000 to SAR 200000, but these are not actual selling prices and tend to be higher. Considering the higher mileage and the time since the last sale, a reasonable estimate would be slightly lower than the SAR 186000 selling price.
