To estimate the price of the 2015 Hyundai Accent I4 1.6L Diesel Kappa (Base), I first considered the accepted offer for a 2016 Hyundai Accent I4 1.6L Diesel with 269,000 km at SAR 25,000. This car is similar in engine and specs but has higher mileage and is a year newer. The listed price for a 2017 model with 263,500 km is SAR 34,500, and for a 2016 model with 269,000 km is SAR 27,000. The 2015 model has lower mileage at 158,000 km, which is a positive factor. Considering the depreciation and the fact that the 2015 model is older but in good condition, I estimate its market price to be slightly lower than the 2016 accepted offer but higher than the lower listed price, balancing between these data points.
