First, I considered the selling prices of similar cars. A 2017 Renault Koleos 2.5L SE (Mid) with 116900 km in good condition sold for AED 38000 on 2024-02-10. Another 2017 Renault Koleos 2.5L LE (Top) with 109800 km in average condition sold for AED 41000 on 2024-04-01. Given that the target car is in average condition and has higher mileage (128500 km), its value should be slightly lower than these. Next, I looked at offers accepted by sellers. A 2017 Renault Koleos 2.5L LE (Top) with 157000 km had an offer accepted for AED 36500 on 2024-02-19, and another with 109800 km had an offer accepted for AED 43000 on 2024-03-04. These offers suggest a range for the LE (Top) variant, which is generally higher than the SE (Mid) variant. Finally, I reviewed listed prices. A 2017 Renault Koleos SE (Mid) with 128500 km was listed for AED 42000, and another with 130850 km was listed for AED 51000 but delisted on 2024-07-03. Considering these data points and the car's condition and mileage, I estimated the market price accordingly.
