I started by looking at the selling prices of similar cars. The first car, a 2018 Alfa Romeo Stelvio Quadrifoglio with 82000 km mileage, sold for 90000 SAR in February 2024. The second car, also a 2018 Alfa Romeo Stelvio Quadrifoglio but with 35000 km mileage, sold for 104500 SAR in July 2024. Given the target car's mileage of 75000 km, its value should be closer to the first car but slightly higher due to lower mileage. Next, I considered the listed prices. The closest match is a car with 75000 km listed for 106000 SAR, but listed prices are generally higher than selling prices. Other listed prices range from 87500 to 109000 SAR. Considering the selling prices and the listed prices, I estimated the market price of the target car.
