To estimate the price of the 2017 Hyundai Tucson I4 2.0L Turbocharged (Diesel) Premium (Top) with 189500 km mileage, I considered the following data points: 1. Selling prices of similar cars: A 2019 Hyundai Tucson I4 1.6L (Diesel) with 24300 km sold for 71000 SAR on 2023-08-19, and another 2019 Hyundai Tucson I4 1.6L (Diesel) with 123879 km sold for 62000 SAR on 2024-08-11. These cars are newer and have lower mileage, so their prices are higher. 2. Listed prices of similar cars: A 2016 Hyundai Tucson I4 2.0L (Diesel) Comfort 4WD with 184500 km was listed for 46500 SAR, and a 2018 Hyundai Tucson I4 2.0L (Diesel) Smart with 178000 km was listed for 53500 SAR. These listings provide a range for older models with similar mileage. 3. Considering the car's age, mileage, and trim level, I adjusted the price downwards from the newer models' selling prices and compared it with the listed prices of older models. The 2017 model with higher mileage and a top trim level should be priced slightly higher than the 2016 model but lower than the 2018 model.
