To estimate the price of the 2015 Nissan Sunny I4 1.5L S A/T (Base) with 313,000 km mileage, I first considered the selling prices of similar cars. A 2016 model with 164,000 km sold for 22,000 SAR in April 2023, and a 2013 model with 185,000 km sold for 13,000 SAR in June 2024. A 2014 model in good condition with 159,000 km sold for 22,500 SAR in August 2024. The 2015 model has higher mileage and is in average condition, suggesting a lower price than these examples. Next, I reviewed listed prices: a 2016 model with 357,500 km was listed for 21,000 SAR, and another with 358,000 km for 22,000 SAR, both delisted recently. These listings suggest a market range for high-mileage cars. Considering the 2015 model's higher mileage and average condition, I estimate its market price to be slightly lower than these listings.
