To estimate the price of the 2012 GMC Acadia V6 3.6L SLT2 (AWD) (Mid+), I considered several data points. First, I looked at the selling prices of similar cars. The most relevant data points are: a 2012 GMC Acadia SLT2 (AWD) (Mid+) with 177775 km sold for 25000 SAR on 2024-01-03, a 2012 GMC Acadia SLT2 (AWD) (Mid+) with 185000 km sold for 15000 SAR on 2024-05-13, and a 2012 GMC Acadia SLT2 (AWD) (Mid+) with 127000 km sold for 32500 SAR on 2024-01-22. Given the mileage and condition of the target car, the most comparable is the one with 177775 km sold for 25000 SAR. The car with 185000 km sold for 15000 SAR, but it might have had other issues not specified. The listed prices of similar cars are 24500 SAR and 30000 SAR, but these are generally higher than actual selling prices. Considering the average condition and higher mileage of the target car (245000 km), I adjusted the estimate slightly lower than the 25000 SAR benchmark.
