To estimate the price of the 2020 Toyota Corolla I4 1.6L XLI (Base) with 179000 km mileage and average condition, I first looked at the selling prices of similar cars. A similar car with 136593 km and good condition sold for 53000 SAR on 2023-11-07. Another similar car with 149000 km and average condition sold for 51500 SAR on 2024-08-26. Given the higher mileage and average condition of the target car, its value should be lower than these. Next, I reviewed listed prices of similar cars. Cars with higher mileage (186000 km and 190000 km) were listed for 45000 SAR but were delisted, indicating they might not have sold at that price. Other listings ranged from 45000 SAR to 57000 SAR, with lower mileage cars listed at higher prices. Considering the target car's higher mileage and average condition, I estimate its market price to be slightly lower than the lower end of the sold prices and the listed prices.
