To estimate the price of the 2019 Kia Carnival V6 3.3L GDI EX (Mid) with 230,000 km mileage, I first considered the selling prices of similar cars. A 2019 model with 101,000 km sold for 54,000 SAR in September 2024. A 2017 model with 178,000 km sold for 37,000 SAR in April 2024. The 2019 model is more recent and had lower mileage, suggesting a higher value than the 2017 model. However, the target car has significantly higher mileage at 230,000 km, which would decrease its value. The listed prices show a 2019 model with 101,000 km at 54,000 SAR and a 2020 model with 43,000 km at 68,000 SAR. Considering the depreciation due to higher mileage and the time since the last sale, I estimate the market price of the target car to be lower than the 2019 model with 101,000 km but higher than the 2017 model with 178,000 km. Therefore, I estimate the price to be around 45,000 SAR.
