I started by looking at the selling prices of similar cars. A 2016 Nissan Tiida hatchback with 139,000 km sold for AED 22,500 on 2023-09-05, and another with 219,000 km sold for AED 17,000 on 2024-10-10. The car with 139,000 km is closer in mileage to the car in question, but the car with 219,000 km is closer in time. The car in question has 185,509 km, so its value should be between these two. Next, I considered offers accepted by sellers: AED 22,000 for a car with 193,000 km on 2024-02-20 and AED 19,500 for a car with 149,000 km on 2024-06-01. These offers suggest a price range of AED 19,500 to AED 22,000. Finally, I looked at listed prices: AED 23,000 for a car with 193,000 km and AED 20,000 for a car with 149,000 km. Considering all data points, the car's estimated market price is around AED 20,000.
