To estimate the price of the 2021 Toyota Yaris I4 1.5L Y (CVT) (Mid) with 89000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars. The closest match is a 2020 Yaris I4 1.5L Y (CVT) (Mid) with 171000 km sold for 36500 SAR on 2024-05-09. Another 2020 Yaris I4 1.5L Y (CVT) (Mid) with 117000 km sold for 37000 SAR on 2024-08-03. A 2019 Yaris I4 1.5L Y (CVT) (Mid) with 47000 km sold for 41000 SAR on 2024-06-28. Considering the mileage and condition, the 2021 model should be priced slightly higher than the 2020 models but lower than the 2019 model with lower mileage. I also reviewed listed prices: a 2021 Yaris I4 1.5L Y (CVT) (Mid) with 76000 km was listed for 45500 SAR but delisted on 2024-07-30. Given the average condition and higher mileage of the target car, I adjusted the price downwards from the listed prices. Combining these factors, I arrived at the final estimate.
