To estimate the price of the 2023 Peugeot 508 GT (Top) with 40000 km mileage, I first considered the selling price of a similar 2022 Peugeot 508 Allure (Base) with 56200 km, which sold for AED 79500 on 2024-01-02. Given that the GT variant is higher than the Allure, I adjusted the price upwards. The new car prices for 2024 models show a difference of AED 20000 between the Allure and GT variants (AED 119900 vs AED 129900). Applying this difference, the estimated price for a 2023 GT variant would be higher. I also looked at listed prices: a 2023 GT with 40000 km is listed for AED 109750, and a 2022 GT with 43900 km was listed for AED 89000. Considering depreciation and the average condition, I adjusted the price downwards from the listed price. Factoring in all these data points, I arrived at the final estimate.
