To estimate the price of the 2016 Mazda 6 I4 2.5L V Grade (Mid) with 189600 km mileage, I first looked at the selling prices of similar cars. The closest match is the 2014 Mazda 6 2.5L V Grade (Mid) with 119000 km, sold for 30574 AED and 30500 AED in late 2023. Considering the 2-year difference and higher mileage, the value should be lower. The 2018 Mazda 6 2.5L V Grade (Mid) with 122869 km sold for 35500 AED in May 2024, and another 2018 model with 44750 km sold for 55000 AED in April 2024. These prices are higher due to the newer model year and lower mileage. The 2016 Mazda 6 2.0L S Grade (Base) with 133200 km sold for 36000 AED in December 2023, but it is a lower trim. The accepted offer for a 2016 Mazda 6 2.5 R Grade (Top) with 155000 km was 30000 AED in September 2024, indicating a lower market value for higher mileage. Considering all these factors, I adjusted the price downwards for the higher mileage and average condition of the target car.
