I started by looking at the selling price of a similar car: a 2013 Mercedes E200 I4 2.0L Turbocharged with 176000 km mileage, which sold for SAR 47500 in February 2024. Given that the car to be estimated has a slightly smaller engine (1.8L) and higher mileage (191000 km), I adjusted the price downwards. Next, I considered the listed prices of similar cars. The closest match is a 2013 Mercedes E200 I4 1.8L Turbocharged with the same mileage listed for SAR 45000. Other listings for 2014 models with similar specs and higher prices were noted but not heavily weighted due to the model year difference. Based on these data points, I estimated the market price by slightly adjusting the selling price downwards to account for the higher mileage and smaller engine size.
