To estimate the price of the 2016 Hyundai Elantra I4 1.6L GLS (Top) with 253000 km mileage, I considered the following data points: 1. A 2016 Hyundai Elantra I4 1.6L Smart (Base) with 297000 km sold for 28000 SAR on 2024-01-08. 2. A 2016 Hyundai Elantra I4 1.6L Smart (Base) with 139800 km sold for 27000 SAR on 2023-09-27. 3. A 2017 Hyundai Elantra I4 1.6L Smart (Base) with 203000 km sold for 29000 SAR on 2024-06-25. 4. A 2016 Hyundai Elantra I4 2.0L GLS (Top) with 100000 km sold for 40000 SAR on 2024-07-02 and 2024-07-05. 5. A 2016 Hyundai Elantra I4 2.0L GL (Mid) with 185000 km sold for 35000 SAR on 2024-02-10. 6. A 2016 Hyundai Elantra I4 2.0L GLS (Top) with 251500 km was listed for 36500 SAR but delisted on 2024-02-24. Considering the higher trim (GLS Top) and the higher mileage of the target car, I adjusted the price downwards from the higher selling prices of the GLS Top variants and factored in the average condition and higher mileage compared to the listed and sold cars.
