I started by analyzing the selling prices of similar 2017 BMW 530 models. The prices ranged from SAR 73,000 to SAR 96,000, with the higher price for a car in good condition and lower mileage. The 2018 model should be valued higher due to being a year newer and having lower mileage. The listed prices for 2018 models ranged from SAR 109,000 to SAR 189,000, but these are typically higher than actual selling prices. The most relevant listing was SAR 140,000 for a similar mileage car. Considering depreciation and the condition of the car, I estimated the market price slightly below the lower end of the listed prices, taking into account the actual selling prices of the 2017 models.
