I started by looking at the selling prices of similar cars. The most relevant data point is the 2015 Nissan Altima SV 2.5L (Mid) with 205,000 km sold for AED 19,500 on 2023-07-10. This car is very similar in variant and condition to the target car. Another relevant data point is the 2015 Altima SL 2.5L (Top) with 202,200 km sold for AED 22,500 on 2024-01-11, but this is a higher trim. The 2015 Altima SL 2.5L (Top) with 190,100 km sold for AED 31,500 on 2023-10-08, but this is also a higher trim and has lower mileage. The accepted offers show a 2015 Altima SE 2.5L (Base) with 236,500 km accepted for AED 19,500 on 2024-02-02, which is a lower trim. The listed prices show a 2015 Altima SV 2.5L (Mid) with 225,000 km listed for AED 18,000, delisted on 2024-04-17. Considering the target car's higher mileage of 239,500 km and average condition, I estimate the market price to be slightly lower than the AED 19,500 selling price of the similar SV variant due to higher mileage.
