To estimate the price of the 2020 Hyundai Sonata I4 2.5L Smart (Mid), I considered the listed prices of similar cars. The 2019 Hyundai Sonata I4 1.7L Diesel Smart (Mid) with 79000 km is listed for SAR 50000. The 2020 Hyundai Sonata I4 1.6L Turbo Charged Premium (Top+) with 81000 km is listed for SAR 65000. The 2019 Hyundai Sonata I4 2.0L Classic (Mid+) with 97000 km is listed for SAR 58000. The 2018 Hyundai Sonata I4 2.4L Supreme (Top) with 253000 km is listed for SAR 39500. The target car is a 2020 model with a 2.5L engine, which is larger than the 1.7L and 2.0L engines but smaller than the 1.6L Turbo. Considering the year, mileage, and engine size, the price should be higher than the 2019 models but lower than the 2020 Turbo model. Therefore, I estimate the price to be around SAR 60000.
