The car to be estimated is a 2023 Mercedes S500 V6 3.0L Twin Turbo with American specs. There are no direct selling prices or offers accepted for similar cars, so we rely on listed prices and new car prices. A 2021 Mercedes S500 with European specs and higher mileage is listed for SAR 524500. Considering the 2023 model is newer and has lower mileage, it should be valued higher. The new car prices for different variants of the S-Class start from SAR 594685. Assuming a 15% annual depreciation, the 2023 model would have depreciated by approximately 15% from its new price. However, the American specs might slightly lower the value compared to Saudi specs. Balancing these factors, the estimated market price is slightly above the listed 2021 model but below the new car price after depreciation.
