To estimate the price of the 2023 Mazda 6 S 2.5L S Grade (Base+), I first looked at the selling price of a similar car: a 2023 Mazda 6 2.5L V Grade (Mid) with 16731 km sold for AED 75000 on 2024-07-15. This car is a higher trim than the S Grade. Next, I considered the new car prices: the 2024 Mazda 6 2.5L S starts at AED 85000. Given that the car in question is a 2023 model, I applied a 10% depreciation for one year, resulting in an estimated new value of AED 76500. I also reviewed offers accepted by sellers: a 2023 Mazda 6 2.5L R Grade (Top) with 30350 km had an offer accepted at AED 66000 on 2024-05-14, and a 2023 Mazda 6 2.5L V Grade (Mid) with 45720 km had an offer accepted at AED 60000 on 2024-07-16. Considering the car's mileage of 37000 km and its base trim, I adjusted the price downwards from the mid-trim selling price and offers accepted. Finally, I factored in the dealer-sold price of a 2023 Mazda 6 2.5L V with 19196 km for AED 72241.5 on 2024-03-16, which is also a higher trim. Based on these data points, I estimated the market price for the 2023 Mazda 6 S 2.5L S Grade (Base+).
