To estimate the price of the 2021 Hyundai Sonata GL (Base) with 27000 miles, I first looked at the selling prices of similar cars. The 2019 Hyundai Sonata GL (Base) with 37000 miles sold for AED 30000 on 2023-12-29. Considering the 2-year difference and assuming a 10% annual depreciation, the 2021 model would be worth more. The 2019 Hyundai Sonata GLS (Top) with 94200 miles sold for AED 31500 on 2024-02-17, but this is a higher trim and has more mileage, so it's less relevant. Next, I reviewed listed prices: a 2021 Hyundai Sonata SE 2.5L i4 GL (Base) with 22000 miles was listed for AED 46500, and a 2020 Hyundai Sonata GL (Mid) with 33000 miles was listed for AED 49000. These listings suggest a higher market value for newer models. Considering the average condition and mileage of the target car, I adjusted the estimate slightly lower than the listed prices but higher than the older sold prices.
