To estimate the price of the 2020 Hyundai Elantra I4 1.6L Smart (Base), I first considered the selling price of a similar 2020 Hyundai Elantra I4 2.0L GLS (Top) with 103,000 km sold for SAR 64,500 in April 2024. This car is a higher trim and has a larger engine, so it would typically sell for more than the 1.6L Smart (Base). Next, I looked at the listed prices of similar cars. A 2020 Hyundai Elantra I4 2.0L Smart (Base) with 150,000 km is listed for SAR 46,000, and another with 180,000 km is listed for SAR 44,500. For the 1.6L Smart (Base), a car with 114,000 km is listed for SAR 55,000, while one with 189,000 km is listed for SAR 45,000, and another with 196,000 km is listed for SAR 35,500. The car with 150,201 km should be priced lower than the 114,000 km car but higher than the 196,000 km car. Considering these factors, I estimate the market price to be slightly below the average of the listed prices for similar mileage and condition.
