To estimate the price of the 2022 MG RX8 I4 2.0L Turbo Charged Luxury (Top) with 15000 km mileage, I analyzed the selling prices of similar cars. The most relevant data points are: 1) A similar car with 18000 km sold for 74500 SAR on 2024-05-21. 2) Another with 10000 km sold for 81000 SAR on 2024-06-10. 3) A car with 20000 km sold for 60000 SAR on 2024-08-15. 4) A car with 500 km sold for 91000 SAR on 2024-07-02. Considering the mileage and condition, the car with 15000 km should be priced between the 74500 SAR and 81000 SAR range. The listed prices of similar cars also support this range, with prices varying from 68000 SAR to 105500 SAR. Given the data, I estimate the market price to be closer to the higher end of the selling prices due to the relatively low mileage and good condition.
