I started by looking at the selling prices of similar cars. The most relevant data point is the 2023 MG 5 I4 1.5L STD (Base) with 12000 km mileage, sold for 34000 SAR on 2024-07-01. This car is very similar to the target car in terms of model year, variant, and condition, but has higher mileage. Another relevant data point is the 2024 MG 5 I4 1.5L STD (Base) with 28000 km mileage, sold for 37500 SAR on 2024-05-31. This car is newer but has significantly higher mileage. Considering the target car has only 6700 km, it should be valued higher than the 34000 SAR car but possibly lower than the 37500 SAR car. I also considered the listed prices of similar cars, which range from 37500 SAR to 43500 SAR, but these are generally higher than actual selling prices. Therefore, I estimated the market price to be slightly above the 34000 SAR car but below the 37500 SAR car.
