I started by examining the selling prices of similar cars. The most relevant data point is the 2023 Hyundai Elantra I4 2.0L Smart (Base) with 4000 km sold for 75000 SAR on 1 Oct 2024. Another 2024 Elantra I4 1.6L GL (Mid) with 1454 km sold for 76500 SAR on 13 Nov 2024. The 2024 Elantra I4 2.0L GL (Mid) with 32000 km sold for 78000 SAR on 6 Oct 2024. The 2024 Elantra I4 2.0L Smart (Base) with 38600 km sold for 65000 SAR on 17 Jul 2024, but it was in average condition. The 2021 Elantra I4 2.0L GL (Mid) with 104000 km sold for 47500 SAR on 29 Jun 2024. The listed prices for similar 2023 Elantra I4 1.6L Smart (Base) cars were 62000 SAR, 74000 SAR, and 59000 SAR, but these are not actual selling prices. Considering the selling prices, the 2023 Elantra I4 1.6L Smart (Base) with 45500 km in good condition should be valued slightly lower than the 75000 SAR for the 2.0L variant due to the smaller engine size and higher mileage, but higher than the 65000 SAR for the average condition car. Therefore, I estimate the market price to be around 70000 SAR.
