To estimate the price of the 2016 GMC Acadia Denali V6 3.6L with 77300 km mileage, I first looked at the selling prices of similar cars. A 2016 GMC Acadia Denali with 104200 km sold for AED 54000 on 2023-10-31. Given the lower mileage of the target car, it should be valued higher. A 2017 Acadia SLE2 with 124000 km sold for AED 53000 on 2023-09-29, but this is a lower trim. A 2018 Acadia SLE with 79500 km sold for AED 62000 on 2023-12-10, but it is a newer model and a lower trim. For listed prices, a 2016 Acadia Denali with 104200 km was listed for AED 54000, and a 2016 Acadia Denali with 143800 km was listed for AED 51500. Considering the lower mileage and the Denali trim, the target car should be valued slightly higher than these listings. Factoring in the condition and the market trends, I estimate the price accordingly.
