Excellent 👍 vehicle, very smooth ,very comfortable ,very reliable. Ultimately, these types of cars feel great and perform exceptionally well—quite apart from their high-quality systems and equipment.

The stereo system is low budget. Needs more quality , it couldn’t hurt considering the price for the vehicle.

My new/used 2018 Acadia is just what I was looking for. It has mostly all the bells and whistles. I thought it had a heated steering wheel, but I cant locate the button for it. Otherwise the 1 owner who owned it before me took really good care of it and it is very very tight! Nice find for me

Reviewed a 2018 GMC Acadia on Feb 23, 2022
I love my 2018 Acadia. I bought it in 2020 as a CPO vehicle, and it felt and looked brand new. My previous car was an 05 BMW X5 and drove like a sports car. I needed my next SUV to handle the road similarly and it had to be towable. It checked off those boxes easily. I also wanted a 3rd row seat. And the 2nd row seats had to be a bench seat to accommodate my 120lb dog. On top of all that, it had to be reliable!! I LOVE my Acadia and would recommend it to anyone.
