To estimate the price of the 2018 Renault Duster I4 2.0L SE 4x4 (Top) with 120000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars. The closest match is a 2018 Renault Duster 2.0L SE (Top) with 56400 km sold for AED 31500 on 2023-11-03. Given the higher mileage of the target car, I adjusted the price downwards. Another relevant data point is a 2018 Renault Duster 2.0L PE (Base) with 149000 km sold for AED 17500 on 2024-07-06. Since the target car is a higher trim (SE) and has lower mileage, its value should be higher. Additionally, a dealer sold a 2018 Renault Duster 2.0L SE with 90925 km for AED 33991.5 on 2023-12-12, which supports a higher valuation for the SE trim. Considering the listed price of a similar car at AED 23500, I adjusted for the actual market conditions and mileage differences. Combining these factors, I arrived at the final estimate.
