To estimate the price of the 2018 Infiniti Q50 I4 2.0L Turbocharged Premium (Mid) with 104612 km mileage, I focused on the selling prices of similar cars. The most relevant data point is a 2018 Infiniti Q50 I4 2.0L Premium (Mid) with 90000 km sold for AED 50000 on 2024-07-19. Given the similar variant and condition, this is a strong indicator. Another Premium (Mid) variant with 59000 km sold for AED 75000 on 2023-08-31, but the lower mileage justifies a higher price. Considering the mileage of the target car is higher than the AED 50000 car, I adjusted the estimate slightly lower. The Red Sport variant sold for AED 55000, but it's a higher trim, so the Premium (Mid) should be less. The Turbo (Base) variant sold for AED 61000 and AED 62000, but these are different trims. Based on these comparisons, the estimated market price is slightly below AED 50000.
