To estimate the price of the 2017 Mercedes GLE63 AMG S V8 5.5L BiTurbo S (Top) with 35500 km mileage, I considered the listed prices of similar cars. The closest match is the 2016 Mercedes GLE63 AMG S V8 5.5L BiTurbo S (Top) with 109600 km listed for SAR 190000. Given the lower mileage of the target car, it should be valued higher. The 2018 models listed range from SAR 193000 to SAR 251000, but they have significantly higher mileage (102000 to 159000 km). Adjusting for the lower mileage and the fact that the target car is a 2017 model, I estimate the price to be slightly higher than the 2016 model but lower than the 2018 models. Considering these factors, I estimate the market price to be around SAR 220000.
