To estimate the price of the 2020 Mercedes GLC200 I4 2.0L Turbocharged Standard with 60500 km mileage, I considered the listed prices of similar cars. The closest match is a 2020 Mercedes GLC200 with the same specifications and mileage listed for SAR 187000. Additionally, I looked at 2021 models with different mileages: one with 18500 km listed for SAR 218000 and another with 110000 km listed for SAR 185500. Given that the 2020 model is listed for SAR 187000 and considering the depreciation and mileage differences, I estimate the market price to be slightly lower than the listed price to account for negotiation and actual selling trends.
