I have one, purchased in 2017, used for pulling boats and RVs. It ran more than 50,000 kilometers, with strong power, low fuel consumption, and no trouble. It is a very very good car.

Only issue I have is not GM’s fault. The emissions system hinders this truck’s true potential. Otherwise it has done everything I’ve ever asked it to.
