GMC builds a handful of Sierra pickups in Canada, and sources a third of its Yukon XL models from Mexico, but otherwise builds everything here in the United States, making it a shame that the product isn’t truly “professional grade.” All current GMC models are either aging rapidly or aren’t considered to be competitive in their classes -- though this Yukon Denali sure is stylish.
