To estimate the price of the 2017 Hyundai Elantra I4 1.6L GL (Mid) with 143,000 km mileage, I first considered the selling prices of similar cars. A 2017 Elantra I4 1.6L with 203,000 km sold for 29,000 SAR in June 2024. A 2016 Elantra I4 1.6L with 122,600 km sold for 37,000 SAR in August 2023. A 2016 Elantra I4 1.6L with 167,430 km sold for 31,500 SAR in August 2023. These prices suggest a range between 29,000 and 37,000 SAR for similar models. The 2017 model year and the GL (Mid) trim might command a slightly higher price than the base variant. The listed price of a similar 2017 Elantra I4 1.6L GL (Mid) with 127,000 km was 32,500 SAR, which aligns with the selling prices. Considering the car's average condition and mileage, I estimate the market price to be slightly lower than the listed price but within the range of recent sales.
