To estimate the price of the 2020 Nissan Micra I4 1.5L Standard with 199100 km mileage, I first looked at the actual selling price of a similar car: AED 21000 for a 2020 Nissan Micra 1.5L I4 with 96000 km sold in March 2024. Given the higher mileage of the target car, I adjusted the price downwards. Next, I reviewed listed prices of similar cars with varying mileages. The closest match in terms of mileage was a car listed for AED 17000 with 131300 km. Considering the target car's significantly higher mileage, I further adjusted the price downwards. The listed prices for cars with lower mileages (e.g., 103000 km listed for AED 25000) also supported a lower estimate for the target car. Finally, I considered the general trend of listed prices, which ranged from AED 17000 to AED 35990, and adjusted for the high mileage and average condition of the target car.
