To estimate the price of the 2014 Infiniti Q50 I4 2.0L Turbocharged Sport (Top) with 224000 km mileage in average condition, I considered the following data points: 1) A 2015 Infiniti Q50 I4 2.0L Sport (Top) with 145000 km in good condition sold for SAR 45000 on 2023-04-30. Adjusting for the higher mileage and average condition, the price would be lower. 2) A 2016 Infiniti Q50 I4 2.0L Turbocharged Sensory (Mid) with 218000 km in good condition sold for SAR 35500 on 2024-09-21. Given the similar mileage but lower trim, the price for the Sport (Top) variant would be slightly higher. 3) Listed prices include a 2016 Infiniti Q50 I4 2.0L Sensory (Mid) with 218000 km for SAR 39000 and a 2015 Infiniti Q50 V6 3.7L Sport (Top) with 154000 km for SAR 42000. Considering these factors, I adjusted the price downwards for the older model year, higher mileage, and average condition.
