To estimate the price of the 2018 Audi Q3 S line I4 2.0L Quattro 35 TFSI (Mid), I first considered the new car price for the 2025 Audi Q3 35 TFSI S-line (150 HP) which is AED 159075. Applying a 10% annual depreciation over 6 years (2018 to 2024), the estimated value is AED 159075 * (0.9^6) = AED 88500. Next, I looked at the accepted offer for a 2020 Audi Q3 2.0L I4 with 14146 miles at AED 88000 in 2023. Adjusting for the older model year and higher mileage, the value would be lower. I also reviewed listed prices of similar 2018 models: AED 52500 for a 40 TFSI with 92741 miles, and classified listings ranging from AED 52000 to AED 85000. Considering the average condition and mileage of the target car, I estimated the market price to be slightly above the lower end of the listed prices but below the average of the classified listings.
