I started by examining the selling prices of similar cars. The most relevant data point is the 2018 Nissan X-Trail SL 2.5L I4 with 76,000 km sold for AED 75,000 on 2023-11-25. Another similar car with 57,900 km sold for AED 76,000 on 2024-02-12. A car with higher mileage of 93,500 km sold for AED 71,000 on 2023-07-12. The car with the closest condition and mileage to the target car is the one with 106,229 km sold for AED 53,000 on 2024-08-10, but it is a lower variant. Considering the target car's average condition and 87,000 km mileage, I adjusted the price downwards from the top variant prices. The accepted offer of AED 76,500 for a similar variant with 57,900 km on 2024-02-06 also supports a higher price range. Dealer sales for SL variants were around AED 67,991.5, but with higher mileage. Taking all these into account, I estimated the market price for the target car.
