To estimate the price of the 2019 Hyundai Tucson I4 2.0L (Diesel) Comfort 2WD (Mid) with 40,000 km mileage, I first considered the selling prices of similar cars. A 2019 Tucson with a 1.6L engine and 24,300 km sold for 71,000 SAR in August 2023, and another with 123,879 km sold for 62,000 SAR in August 2024. A 2020 model with a 2.0L engine and 34,866 km sold for 71,500 SAR in September 2024. The 2018 model with a 2.0L turbo engine and 115,100 km sold for 55,500 SAR in October 2024. The 2020 model is closest in engine size and condition, suggesting a price around 71,500 SAR. Considering the 2019 model's lower mileage and good condition, it should be valued slightly higher than the 2019 1.6L models but slightly lower than the 2020 2.0L model. Listed prices for similar 2019 models range from 58,500 to 65,500 SAR, with a 2.0L model listed at 58,500 SAR. Given these data points, the estimated market price is adjusted to reflect the car's good condition and lower mileage.
