To estimate the price of the 2018 Hyundai Sonata I4 2.4L Supreme (Top) in good condition, I first considered the selling prices of similar cars. The most relevant data point is a 2018 Sonata Smart (Mid) with good condition sold for 51500 SAR on 2024-10-06. This car is a lower trim than the Supreme but in similar condition. Other Smart (Mid) variants in average condition sold for between 32000 and 59000 SAR, with the most recent sale at 51500 SAR. The Supreme trim should be valued higher than the Smart (Mid) due to its higher specification. I also considered listed prices for the Supreme variant, which were 53500 SAR and 46500 SAR, though these are typically higher than actual selling prices. Given the good condition and higher trim level, I estimate the market price to be slightly above the highest recent sale of a Smart (Mid) in good condition.
