I started by examining the selling prices of similar cars. The most relevant data point is the 2023 Chevrolet Captiva 1.5L TC I4 LT FWD (Base) with 56000 km sold for 55000 AED on 2024-02-04. Another similar car with 21159 km sold for 60000 AED on 2024-04-18. The car in question has 40800 km, which is between these two. Considering the condition is average, I adjusted the price slightly lower than the 55000 AED car due to higher mileage and average condition. The accepted offer for a similar variant with 21159 km was 60000 AED on 2024-04-06, which supports the 60000 AED selling price. However, given the average condition and higher mileage, I estimated a lower price.
