To estimate the price of the 2022 MG RX8 I4 2.0L Turbocharged Luxury (Top) with 126000 km mileage, I primarily considered the selling prices of similar cars. The closest match is a 2022 MG RX8 Luxury (Top) with 66000 km sold for 72000 SAR on 2024-06-22. Another 2022 model with 18000 km sold for 74500 SAR on 2024-05-21. A 2022 model with 10000 km sold for 81000 SAR on 2024-06-10. Given the higher mileage of the target car, I adjusted the price downwards. A 2020 model with 134000 km sold for 53000 SAR on 2024-06-19, and a 2020 model with 137000 km sold for 52500 SAR on 2023-09-06. Considering the depreciation and mileage, I estimated the price to be lower than the 2022 models with lower mileage but higher than the older 2020 models.
