Summary
With 2,725 currently listed for sale and an average price of $16,306.00, 32.1% of 2018 GMC Acadias for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 GMC Acadia 4.79 / 5 stars.

The 2018 GMC Acadia offers a spacious and comfortable interior, with the option for V6 power now available to more trims, increasing its versatility for families and those needing more power.
Why it stands out
The 2018 GMC Acadia impresses with its spacious interior and array of safety features, making it a popular choice among families. Its updated design from previous years enhances its comfort and ride quality, successfully focusing on passenger experience. The availability of the robust 3.6-liter V6 engine for more trims significantly boosts performance, addressing the earlier inefficacy of the base 4-cylinder engine. Despite its appeal, some owners have raised concerns regarding the limited trunk space and overall cost of ownership. Additionally, while the Acadia retains solid safety ratings, potential buyers should be aware of some reduced towing capacity compared to older models. Overall, the Acadia strikes a balance between family-friendly utility and capable performance.

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

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.
