I am certainly not a specialist when it comes to cars.
I would have never expected that these (2010) models would come with 2WD only according to what i found on the internet. I even looked up the 2023 models on the official GMC website , and found these models are available in 2Wd or 4WD.
I would never buy such a model with rear wheel drive only.
Such a waste. Too costly and too large for the city.
If i would buy such a car for outside the city, country side : definitely always the 2WD (Best for highway), 4WD or AWD for the off road situations or heavy load pulls.
