To estimate the price of the 2021 Chevrolet Captiva Premier I4 1.5L Turbo Charged LTZ (Top) with 51000 km mileage, I first looked at the selling prices of similar cars. The closest match in terms of variant and condition is the LT AWD (Mid) variant, which sold for prices ranging from 40000 to 47000 SAR. The LT FWD (Base) variant sold for 50000 SAR but is a lower trim. The LTZ (Top) variant listed for 47002 SAR and 58000 SAR, but these are listing prices and generally higher than selling prices. Considering the LTZ (Top) is a higher trim than LT AWD (Mid) and the average condition of the car, I adjusted the price upwards from the LT AWD (Mid) selling prices.
