To estimate the price of the 2020 Chevrolet Tahoe V8 5.3L LS 2WD (Base) with 81500 km mileage and average condition, I first considered the selling prices of similar cars. A 2020 Tahoe LS 4WD (Base+) with 177000 km sold for 96000 SAR, but it has higher mileage and a different drivetrain. A 2021 Tahoe LS 2WD (Base) with 32000 km and good condition sold for 170000 SAR, indicating a higher value for newer models with lower mileage. The listed prices for 2020 Tahoe LS 2WD (Base) with similar mileage are 147500 SAR and 143500 SAR, but these are not actual selling prices. Considering the car's average condition and mileage, I adjusted the estimate downwards from the listed prices. The 2020 model's average condition and higher mileage compared to the 2021 model suggest a lower price than the 170000 SAR selling price of the 2021 model. Balancing these factors, I estimated the market price for the car.
