To estimate the price of the 2018 Chevrolet Tahoe V8 5.3L LS 2WD (Base) with 195000 km mileage and average condition, I considered several data points. The most relevant selling price is a 2018 Chevrolet Tahoe V8 5.3L LS 2WD (Base) with 21000 km sold for 145000 SAR in good condition on 2023-09-28. Adjusting for mileage and condition, the price should be lower. A 2020 model with 133000 km in average condition sold for 120000 SAR on 2024-01-03, and a 2019 model with 227640 km in average condition sold for 103000 SAR on 2024-02-12. The listed prices for similar 2018 models with higher mileage are 93000 SAR and 88000 SAR. Considering these factors, the estimated price should be lower than the 2020 model but higher than the 2019 model with higher mileage.
