To estimate the price of the 2012 Hyundai Sonata I4 2.4L Smart (Mid) with 208000 km mileage in average condition, I first looked at the selling prices of similar cars. A 2012 Hyundai Sonata I4 2.4L Premium (Top+) with 322000 km sold for SAR 22000 on 2024-01-04, and a 2013 Hyundai Sonata I4 2.4L Premium (Top+) with 263583 km sold for SAR 25000 on 2024-08-31. Given that the target car is a mid variant and has lower mileage, it should be priced slightly higher than the first car but lower than the second due to its average condition. Next, I reviewed listed prices of similar cars. A 2012 Hyundai Sonata I4 2.4L Smart (Mid) with the same mileage is listed for SAR 24000, and another with 161200 km is listed for SAR 23500. Considering the average condition and the fact that listed prices are usually higher than selling prices, I adjusted the estimate downwards. Finally, I considered the depreciation and market trends to arrive at a fair market price.
