To estimate the price of the 2015 Hyundai Elantra I4 2.0L GLS (Top) with 173,000 km mileage, I first considered the selling prices of similar cars. A 2016 Elantra I4 2.0L GLS (Top) with 174,000 km sold for 33,000 SAR on 2023-07-17. Another 2016 Elantra I4 2.0L GLS (Top) with 116,000 km sold for 36,500 SAR on 2023-08-27. A 2016 Elantra I4 2.0L GLS (Top) with 100,000 km sold for 40,000 SAR on 2024-07-02. These prices suggest a range for the GLS (Top) variant. The 2015 model is older, so I adjusted for depreciation and higher mileage. The listed price of a similar 2015 Elantra I4 2.0L GLS (Top) with 162,000 km was 21,000 SAR, but it was delisted, indicating it might not have sold at that price. Considering these factors, I estimated the market price for the 2015 model with 173,000 km to be slightly lower than the 2016 models, accounting for age and mileage.
