To estimate the price of the 2012 GMC Acadia Denali, I first considered the selling price of a 2014 GMC Acadia SLE2 (Base) with average condition and 137400 km mileage, which sold for AED 33000 in June 2023. The Denali trim is higher than the SLE2, so it would typically be valued higher. Next, I looked at offers accepted for 2014 Denali variants: AED 38500 for 151500 km and AED 30000 for 145500 km. These are more recent and relevant as they are the same trim. The 2010 SLT2 variant had an accepted offer of AED 18000, but it's older and less relevant. For listed prices, a 2012 SLT2 with 254300 km was listed for AED 15500, and a 2014 Denali with 147000 km was listed for AED 38000. Considering the 2012 Denali's higher mileage of 285000 km and average condition, I adjusted the price downwards from the 2014 Denali offers and listings, factoring in depreciation and mileage.
