To estimate the price of the 2020 Peugeot 508 1.6L Turbo I4 GT line GT (Top) with 39000 km mileage, I considered the following data points: 1. A 2022 Peugeot 508 Active 1.6L TC i4 Allure (Base) with 56200 km sold for AED 79500 on 2024-01-02. This car is newer but has higher mileage and a lower trim. 2. A 2020 Peugeot 508 1.6L Turbo I4 GT line GT (Top) with 39000 km is listed for AED 75000. This is the exact same model and mileage, making it a very relevant comparison. 3. Other listed prices for similar 2020 models with higher mileage range from AED 70000 to AED 89500. Considering the exact match listing and the selling price of a newer but lower trim model, I adjusted the estimate to reflect the market conditions and the specific details of the car in question.
