To estimate the price of the 2016 BYD F3 I4 1.5L Standard, I first considered the selling price of a similar 2018 model with good condition and lower mileage, which sold for SAR 21500 in August 2023. Given the older age and higher mileage of the target car, its value would be lower. Next, I looked at an offer accepted for a 2016 model with similar mileage and condition, which was SAR 15000 in October 2024. This is a strong indicator of the market value. The listed price for a similar 2016 model was SAR 17000, but listed prices are typically higher than actual selling prices. Considering these data points, the accepted offer of SAR 15000 is the most reliable indicator, and I adjusted slightly for the higher mileage and average condition of the target car.
