To estimate the price of the 2021 Hyundai Santa Fe V6 3.5L 4WD (Mid) with 216,000 km mileage, I focused on the selling prices of similar cars. The closest match is the 2020 Hyundai Santa Fe V6 3.5L 4WD GLS (Mid+) with 121,000 km sold for 73,000 SAR on 2023-11-27. Considering the higher mileage of the target car, I expect a lower price. The 2019 model with 139,000 km sold for 77,000 SAR on 2024-05-08, and another 2019 model with 146,000 km sold for 73,000 SAR on 2024-08-03. These suggest a depreciation trend for higher mileage. Given the target car's mileage and average condition, I estimate its price to be slightly lower than these 2019 models, considering the additional mileage and age.
