The car in question is a 2023 GMC Sierra AT4 X V8 6.2L 3500 (Top+). We have no direct selling prices, but we have an offer accepted for a similar 2023 GMC Sierra Denali Ultimate V8 6.2L at AED 283500. The Denali Ultimate is a higher trim than the AT4 X, so the AT4 X should be priced lower. The new car price for a 2025 GMC Sierra 5.3L V8 AT4 Crew Cab (AWD) is AED 271000. The AT4 X with a 6.2L engine would be priced higher than the 5.3L AT4, but less than the Denali Ultimate. Considering depreciation, the 2023 model would be about 15% less than a new 2025 model. Therefore, the estimated price for the 2023 AT4 X should be slightly lower than the Denali offer and adjusted for depreciation from the new price, leading to an estimate of AED 260000.
