To estimate the price of the 2020 Range Rover Evoque S P200 I4 2.0L Turbocharged S (200 PS) AWD (Base) with 55000 km mileage, I considered the listed prices of similar cars. The closest match is a car with the same specifications and mileage listed for SAR 135000. Another similar car with 65000 km was listed for SAR 163500, and another with 74900 km was listed for SAR 190000. Given the average condition of the car in question, I adjusted the price slightly lower than the lowest listed price to account for potential negotiation and the car's condition.
