The most relevant data point is the selling price of a 2018 Mercedes S560 Standard with 51000 km sold for AED 205,000 in August 2023. The car to be estimated is a 2019 model with 49000 km, which is slightly newer and has lower mileage. Considering the depreciation from 2018 to 2019, the 2019 model should be valued slightly higher. The listed prices for 2018 models range from AED 160,000 to AED 270,000, but these are not actual selling prices. Given the selling price of AED 205,000 for the 2018 model, a reasonable estimate for the 2019 model would be slightly higher, accounting for the newer year and lower mileage.
