To estimate the price of the 2020 Mercedes GLE53 AMG V6 3.0L Twin Turbo 4MATIC (Top+), I considered the listed prices of similar cars. The listed prices for 2021 models with similar specs range from SAR 310500 to SAR 387500, with mileage between 9000 km and 112000 km. The 2022 models are listed between SAR 405000 and SAR 430000, with mileage between 14500 km and 26000 km. Given that the car in question is a 2020 model with 135000 km, I adjusted the price downward to account for the older model year and higher mileage. The average price of the 2021 models is around SAR 350000, and considering the depreciation and higher mileage, I estimated the price to be lower.
