To estimate the price of the 2018 Range Rover Velar R-Dynamic I4 2.0L Turbo Charged SE (250 PS) (Mid) with 55000 km mileage, I first looked at the selling prices of similar cars. A similar car with 50000 km sold for 180000 SAR on 2024-05-28, and another with 119000 km sold for 122000 SAR on 2023-08-08. Given the closer mileage and more recent sale, the 180000 SAR is more relevant. Next, I reviewed listed prices: a similar car with 55000 km is listed for 197500 SAR, and another with 50000 km is listed for 183500 SAR. These listings are higher than the actual selling prices, indicating sellers' expectations. Considering the selling price of 180000 SAR and the listed prices, I estimate the market price to be slightly lower than the highest selling price due to the average condition and market trends.
