To estimate the price of the 2020 Nissan Sunny I4 1.5L S A/T (Base) with 105000 km mileage in average condition, I first looked at the selling price of a similar car sold on 2023-12-27 for SAR 36500 with 72000 km mileage. Given the higher mileage of the target car, I adjusted the price downwards. Next, I reviewed listed prices of similar cars with varying mileages: SAR 33000 for 105000 km, SAR 34000 for 96000 km, SAR 33000 for 131000 km, SAR 38500 for 78000 km, SAR 33000 for 73000 km, SAR 37500 for 72000 km, and SAR 36000 for 70000 km. The listed prices for cars with similar or higher mileage ranged from SAR 33000 to SAR 34000. Considering the actual selling price and the listed prices, I estimated the market price for the target car to be slightly lower than the average listed price due to its higher mileage.
