To estimate the price of the 2015 Genesis G80 V6 3.8L Turbocharged 3.5T Platinum (Top) with 204000 km mileage, I considered several data points. First, the 2014 Genesis G80 V6 3.8L Standard with 157200 km sold for SAR 30000 in September 2023. Given the target car is a higher trim and a year newer, it should be valued higher. The 2016 Genesis G80 V8 5.0L Royal (Top+) with 75000 km sold for SAR 75000 in July 2024, but this car has a more powerful engine and lower mileage, so it should be valued higher than the target car. For listed prices, a 2015 Genesis G80 V6 3.8L Turbocharged 3.5T Platinum (Top) with the same mileage is listed for SAR 38500. Considering the car's condition and the fact that listed prices are generally higher than selling prices, the actual market value should be slightly lower. Other listed prices for similar models range from SAR 35000 to SAR 74000, but these vary in mileage and trim. Taking all these factors into account, I estimated the market price accordingly.
