To estimate the price of the 2024 Nissan Sunny 1.5L S (Base) with 78 km mileage, I first looked at the selling price of a similar car: a 2024 Nissan Sunny 1.5L i4 S (Base) with 4700 km sold for AED 44500 on 2024-04-23. Given the lower mileage of the target car, it should be valued slightly higher. Next, I considered the dealer-sold prices of 2024 Nissan Sunny 1.5L SV models with very low mileage (54-58 km) sold for AED 45041.5 in July 2024. Although these are SV variants, the price difference between S and SV trims is minimal. Lastly, I reviewed the listed prices of similar cars, noting that the 2024 Nissan Sunny 1.5L S (Base) with 78 km is listed for AED 69990, which is likely inflated. Considering all these data points, the most accurate estimate is slightly above the selling price of the similar car with higher mileage but below the inflated listing price.
