GMC Acadia 2016 Used Automatic Gasoline For sale: GMC Acadia 2016. I bought it for 25,000, and now I'm selling it to the highest bidder. I need a down payment for a new car. The car is in good condition, no issues. However, I changed the gear oil, which hadn't been changed for a long time. And there's a slight jerk when shifting between second and third gear. The car drives fine, but this is the only observation. Selling to the highest bidder.
