I analyzed the selling prices of similar cars first. The most relevant data points are: 2022 Geely Tugella GF Luxury (Top) with 51700 km sold for 78000 SAR on 2023-11-25, 2022 Geely Tugella GF Luxury (Top) with 28 km sold for 75000 SAR on 2024-05-06, and 2022 Geely Tugella GF Luxury (Top) with 68000 km sold for 75000 SAR on 2024-05-24. The car with 31000 km listed for 82000 SAR is also relevant but not sold. Considering the target car's mileage of 31000 km and good condition, I adjusted the price slightly higher than the average of the sold prices but lower than the highest listed price.
