To estimate the price of the 2018 Chevrolet Tahoe V8 5.3L LS 4WD (Base+), I considered several data points. First, I looked at the selling prices of similar cars. The closest match is a 2019 Chevrolet Tahoe V8 5.3L LS 4WD (Base+) with 227640 km sold for 103000 SAR in February 2024. Given the lower mileage of the target car (80000 km), it should be valued higher. Another relevant data point is a 2020 Chevrolet Tahoe V8 5.3L LS 4WD (Base+) with 111000 km sold for 134000 SAR in January 2024. Considering the target car is older but has lower mileage, its value should be slightly lower. Additionally, a 2018 Chevrolet Tahoe V8 5.3L LS 2WD (Base) with 21000 km sold for 145000 SAR in September 2023, but this car is in better condition and has significantly lower mileage. Finally, the listed price for a similar 2018 model with the same mileage is 125500 SAR, which is likely higher than the actual selling price. Taking all these factors into account, I estimate the market price of the target car to be around 115000 SAR.
