To estimate the price of the 2015 Genesis G90 3.8L V6 Royal, I started with the new car prices for different variants of the 2025 Genesis G90. The closest variant to the 2015 model is the 5.0L V8 Royal, which starts at AED 340,000. Given that car values depreciate by approximately 10% per year, I calculated the depreciation over 9 years (2015 to 2024). The formula for depreciation is: Depreciated Value = Initial Value * (1 - Depreciation Rate)^Number of Years. Using this formula, the estimated value of the 2015 model is AED 340,000 * (1 - 0.10)^9, which equals approximately AED 129,146. Considering the car's high mileage (170,500 km) and average condition, I further adjusted the price downwards by around 20% to account for these factors, resulting in an estimated market price of AED 103,317.
