To estimate the price of the 2021 Mercedes S500 Maybach with 32,000 km mileage and Japanese specs, I considered the listed prices of similar cars. The closest match is a 2021 Mercedes S500 Maybach with 54,000 km listed for AED 370,000. Another 2022 Mercedes S500 Maybach with 16,000 km is listed for AED 450,000. A 2021 Mercedes S500 Standard variant with 15,000 km is listed for AED 363,000. Given the higher mileage of the closest match and the higher price of the newer model, I adjusted the price downwards from the AED 370,000 listing to account for the lower mileage and the fact that listed prices are generally higher than selling prices.
