I started by examining the selling prices of similar cars. The most relevant data point is the 2020 Nissan Sunny 1.5L I4 S (Base) with 83500 km sold for AED 25500 on 2023-10-21. This car is very similar to the target car in terms of variant, engine, and condition. Another similar car with 63000 km sold for AED 32000 on 2023-07-03, but it has lower mileage. The 2020 Nissan Sunny SV (Mid) with 122000 km sold for AED 27800 on 2023-08-20, which is a higher variant but with much higher mileage. The accepted offer for a similar S (Base) variant with 83500 km was AED 27000 on 2023-10-14. Considering these data points, the selling price of AED 25500 for a very similar car is the most reliable indicator. The target car has slightly lower mileage, which could justify a slightly higher price, but the condition is average. Therefore, I estimate the market price to be slightly above AED 25500, considering the mileage and condition.
