To estimate the price of the 2014 Mercedes S550 V8 4.7L Twin Turbo AMG (Top+), I first considered the selling price of a 2016 Mercedes S550 V8 4.7L with 20000 miles sold for SAR 145000 in March 2024. Given the 2-year difference, I applied a depreciation rate of 10% per year, resulting in an approximate value of SAR 118450 for a 2014 model. Next, I looked at listed prices of similar cars: a 2015 model with 115000 miles listed for SAR 145000, a 2014 model with 146500 miles listed for SAR 150000, and a 2014 model with 165000 miles listed for SAR 132000. Considering the higher mileage and the fact that these are listed prices, I adjusted downwards. The 2013 model with 180500 miles listed for SAR 62500 and the 2012 model with 150000 miles listed for SAR 65000 were also considered, but they are older and have higher mileage. Given the target car's mileage of 130000 miles and its AMG (Top+) trim, I estimated its market price to be slightly higher than the average of the listed prices for 2014 models.
