To estimate the price of the 2021 Chevrolet Tahoe V8 5.3L LS 4WD (Base+) with 155,000 km mileage, I focused on the selling prices of similar cars. The most relevant data point is the 2020 Tahoe LS 4WD (Base+) with 111,000 km sold for 134,000 SAR on 2024-01-20. Another 2020 model with 55,000 km sold for 110,000 SAR on 2024-09-09, indicating a lower price due to higher mileage. A 2019 model with 227,640 km sold for 103,000 SAR on 2024-02-12, showing significant depreciation with high mileage. The 2021 model listed prices range from 150,500 to 165,500 SAR, but these are not actual selling prices. Considering the 2021 model's higher mileage and average condition, I adjusted the price downward from the 2020 model's selling price of 134,000 SAR, accounting for the additional year of depreciation and higher mileage.
