To estimate the price of the 2023 MG One I4 1.5L Turbo Charged LUX (Top) with 12500 km mileage, I considered the listed price of a similar car. The listed price for a 2023 MG One I4 1.5L Turbocharged STD (Base) with 46 km mileage is SAR 58000. The LUX (Top) variant is generally more expensive than the STD (Base) variant. Considering the new car price difference between base and top variants, which is typically around 20%, I adjusted the price upwards. Additionally, the mileage of the car to be estimated is higher, which would slightly reduce the price. Factoring in these adjustments, I arrived at the final estimate.
