To estimate the price of the 2017 Mercedes E200 I4 2.0L Twin Turbo Standard with 106000 km mileage, I analyzed the listed prices of similar cars. The closest match is a 2017 model with identical specs and mileage listed for SAR 137500. Other relevant listings include a 2018 model with 151000 km listed for SAR 125500, and another 2018 model with 154000 km listed for SAR 160000. Considering the average condition of the target car, I adjusted the price slightly lower than the 2017 model listed for SAR 137500. The 2016 model with higher mileage (158000 km) listed for SAR 83000 and the 2018 model with very high mileage (200900 km) listed for SAR 73000 were also considered but given less weight due to their higher mileage and older model year.
