To estimate the price of the 2023 Geely Monjaro I4 2.0L Turbocharged Ultimate (Top) with 30239 km mileage, I considered the following data points: 1) Offers accepted by sellers: SAR 111000 for a car with 15000 km on 2024-01-22 and SAR 95500 for a car with 400 km on 2024-08-29. 2) Listed prices: SAR 132000 for a car with 15000 km, SAR 103500 for a car with 400 km, and SAR 121500 for a car with 68800 km. The accepted offers are more reliable, so I gave them more weight. The car with 15000 km was accepted at SAR 111000, and the car with 400 km was accepted at SAR 95500. Considering the higher mileage of the target car (30239 km), I adjusted the price downwards from the SAR 111000 offer. The listed prices also suggest a range between SAR 103500 and SAR 132000, but these are generally higher than actual selling prices.
