To estimate the price of the 2020 Mercedes GLC200 I4 2.0L Turbocharged AMG Line (Top+), I considered the listed prices of similar cars. The closest match is a 2020 Mercedes GLC200 I4 2.0L Turbocharged Standard variant with 62500 km listed for SAR 187000. Given that the car in question is an AMG Line (Top+), which is a higher trim, it would typically command a higher price. The 2021 models listed range from SAR 185500 to SAR 218000, but they are Standard variants and have different mileages. Considering the higher trim and the mileage of 64000 km, I adjusted the price upwards from the 2020 Standard variant listed price to account for the AMG Line (Top+) trim and the market conditions.
