To estimate the price of the 2012 GMC Yukon XL V8 5.3L XL SLE (Base+), I first looked at the selling prices of similar cars. The 2014 GMC Yukon V8 5.3L XL SLE (Base+) with 179000 km sold for SAR 49000 in September 2023. Given that the car in question is a 2012 model with 134000 km, I adjusted for the model year and mileage. The 2013 GMC Yukon V8 6.2L Denali with 213000 km sold for SAR 37000 in May 2024, and the 2013 GMC Yukon V8 6.2L Denali with 255000 km sold for SAR 25000 in April 2024. These Denali variants are higher trims, so their prices are not directly comparable but provide a range. For listed prices, a 2012 GMC Yukon XL V8 5.3L XL SLE (Base+) with 134000 km is listed for SAR 57500, and a 2013 model with 140000 km is listed for SAR 57000. Considering the selling prices and listed prices, I estimated the market price by factoring in the lower trim and average condition of the car in question.
