I analyzed the selling prices of similar 2020 MG RX8 cars, focusing on the Luxury (Top) variant as it matches the car in question. The most relevant data points are: a car with 76000 km sold for 52000 SAR on 2024-04-27, a car with 82000 km sold for 37000 SAR on 2024-09-06, a car with 55083 km sold for 57500 SAR on 2024-09-25 and 2024-10-03, and a car with 106442 km sold for 42000 SAR on 2024-10-20 and 2024-10-21. The car in question has 75362 km, which is closer to the 76000 km car that sold for 52000 SAR. Considering the condition and mileage, I estimate the price to be slightly higher than 52000 SAR but lower than 57500 SAR, given the recent sales and condition.
