To estimate the price of the 2016 Mercedes S400 V6 3.0L Turbocharged Standard with 153999 km mileage, I first looked at the selling prices of similar cars. A 2015 Mercedes S400 with 94000 km sold for AED 112000 in November 2023, and a 2014 Mercedes S400 with 117036 km sold for AED 90000 in June 2024. Given the higher mileage of the 2016 model, I adjusted the price downwards. Next, I reviewed listed prices of similar cars. A 2016 Mercedes S400 with 153999 km is listed for AED 123000, and another 2016 model with 145000 km is listed for AED 119999. Considering these listings are higher than actual selling prices, I adjusted the estimate downwards. Finally, I considered the depreciation and condition of the car to arrive at a fair market price estimate.
