To estimate the price of the 2017 Chevrolet Cruze LS I4 1.8L (Base) with 102,000 km mileage, I first considered the selling prices of similar cars. A 2017 Cruze LS (Base) with 138,000 km sold for 20,000 SAR on 2024-09-13, and another with 197,000 km sold for 14,000 SAR on 2024-05-16. The car with 39,000 km sold for 26,000 SAR on 2024-04-30. The car in question has lower mileage than the 138,000 km car but higher than the 39,000 km car, suggesting a price between 20,000 and 26,000 SAR. The listed price of a similar car with 138,000 km was 22,000 SAR, which aligns with the selling price of 20,000 SAR. Considering the car's good condition and lower mileage, I estimate the price slightly higher than 20,000 SAR.
