To estimate the price of the 2021 Mercedes GLE53 AMG V6 3.0L Twin Turbo Coupe with 9000 km mileage, I considered the listed prices of similar cars. The closest match is a 2021 model with 17000 km listed for SAR 387500. Other 2021 models with higher mileage (67000 km and 112000 km) are listed for SAR 310500 and SAR 329500 respectively. A 2022 model with 14500 km is listed for SAR 430000, and another 2022 model with 26000 km is listed for SAR 405000. Given the lower mileage of the target car (9000 km), it should be valued higher than the 2021 models with higher mileage but lower than the 2022 models. Therefore, I estimate the price to be slightly higher than SAR 387500 but lower than SAR 405000.
