To estimate the price of the 2018 Mercedes GLE63 AMG S V8 5.5L BiTurbo Standard with 105000 km mileage, I considered the listed prices of similar cars. The closest match is a 2018 Mercedes GLE63 AMG V8 5.5L BiTurbo Standard with 102000 km listed for SAR 229500. Another 2018 model with higher mileage (159000 km) is listed for SAR 197500. A 2016 model with similar mileage (109600 km) but a higher trim (S) is listed for SAR 190000. Given the target car's good condition and slightly lower mileage compared to the closest match, I estimate the price to be slightly lower than the SAR 229500 listing but higher than the SAR 197500 listing, considering the mileage and condition.
