The car to be estimated is a 2018 Chevrolet Tahoe LS V8 5.3L LS 4WD (Base+) with 86887 km mileage. The most relevant data point is a 2018 Chevrolet Tahoe V8 5.3L LS 2WD (Base) with 21000 km sold for 145000 SAR on 2023-09-28. This car has lower mileage and is 2WD, which typically sells for less than 4WD. Another relevant data point is a 2019 Chevrolet Tahoe LS 4WD (Base+) with 227640 km sold for 103000 SAR on 2024-02-12. This car has much higher mileage, which significantly reduces its value. A 2020 Chevrolet Tahoe LS 4WD (Base+) with 111000 km sold for 134000 SAR on 2024-01-20, which is newer but has higher mileage. The listed price for a similar 2018 model with 80000 km was 124500 SAR, but it was delisted, indicating it might not have sold at that price. Considering these data points, the estimated price should be slightly lower than the 145000 SAR for the 2WD variant due to higher mileage but higher than the 103000 SAR for the 2019 model with much higher mileage.
