I analyzed the selling prices of similar cars first. The most relevant data points are: 1) A 2012 GMC Acadia V6 3.6L SLE2 (FWD) with 186500 km sold for 20000 SAR on 2023-10-23. 2) Another 2012 GMC Acadia V6 3.6L SLE2 (FWD) with 235000 km sold for 24000 SAR on 2023-11-17. 3) A 2012 GMC Acadia V6 3.6L SLE2 (FWD) with 240900 km sold for 17300 SAR on 2023-08-04. The car in question has 205000 km, which is between the first and second data points. Considering the average condition and mileage, the price should be closer to the first data point but slightly higher due to lower mileage compared to the second data point. The listed prices of similar cars range from 20000 to 27000 SAR, but these are generally higher than actual selling prices. Therefore, I estimate the market price to be slightly above the first data point but below the second data point.
