To estimate the price of the 2018 Hyundai Elantra I4 2.0L GLS (Top) with 196000 km mileage, I first looked at the selling prices of similar cars. The closest match is a 2018 Hyundai Elantra I4 2.0L GLS (Top) with 80000 km sold for 50000 SAR on 2024-05-10. Considering the higher mileage of the target car, I adjusted the price downwards. Another relevant data point is a 2016 Hyundai Elantra I4 2.0L GLS (Top) with 100000 km sold for 40000 SAR on 2024-07-02 and 2024-07-05. Given the target car's higher mileage and being two years newer, I adjusted the price accordingly. The listed prices for similar cars are 47000 SAR and 52000 SAR, but these are typically higher than actual selling prices. Considering all these factors, I estimated the market price by balancing the depreciation due to higher mileage and the newer model year.
