To estimate the price of the 2018 GMC Acadia V6 3.6L SLE2 (FWD) with 327,000 km mileage, I first considered the selling prices of similar cars. A 2016 Acadia SLE2 (FWD) with 208,170 km sold for 37,000 SAR in August 2023, and another 2016 SLE2 (FWD) with 169,000 km sold for 36,224 SAR in May 2024. These cars have lower mileage and are older models, suggesting a lower price for the 2018 model with higher mileage. A 2018 Acadia SLT2 (AWD) with 134,877 km sold for 62,000 SAR in August 2024, but this is a higher trim and lower mileage. For listed prices, a 2018 SLE2 (FWD) with 160,000 km was listed for 52,000 SAR in February 2024, indicating a higher price than expected for the target car due to lower mileage. Considering the high mileage and average condition of the target car, I estimate its market price to be lower than these figures, accounting for depreciation and condition.
