To estimate the price of the 2020 Hyundai Elantra I4 1.6L Smart (Base) with 114000 km mileage, I first looked at the selling prices of similar cars. The closest match is the 2020 Hyundai Elantra I4 2.0L GLS (Top) with 103000 km sold for 64500 SAR on 2024-04-17. Given that the 2.0L GLS (Top) variant is higher than the 1.6L Smart (Base), I adjusted the price downwards. Another relevant data point is the 2021 Hyundai Elantra I4 2.0L GL (Mid) with 104000 km sold for 47500 SAR on 2024-06-29, which is a mid variant and slightly newer. Considering the 1.6L Smart (Base) is a lower variant, I adjusted the price further down. The listed prices for similar 2020 Hyundai Elantra I4 1.6L Smart (Base) models range from 54000 to 55000 SAR, but these are typically higher than actual selling prices. Taking all these factors into account, I estimated the market price accordingly.
