Summary
With 2,756 currently listed for sale and an average price of $16,128.00, 32.0% 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.
61.4% of 2018 Acadia models on CarGurus are accident free.
The 2018 GMC Acadia offers a spacious interior with a variety of features, making it an appealing choice for families, particularly with its available V6 engine for improved performance and the introduction of second-row captain's chairs for added comfort.
Why it stands out
The 2018 GMC Acadia distinguishes itself in the competitive midsize SUV segment with a perfect balance of practicality, comfort, and family-friendly features. One of the standout attributes is its spacious interior that allows for flexibility in seating arrangements, thanks to available captain’s chairs in the second row. This not only enhances comfort but also facilitates easier access to the third row. The strong optional V6 engine brings a significant boost in performance, which is crucial for those intending to tow or carry larger loads, transforming the driving experience from merely functional to engaging.
Despite its competitive advantages, potential buyers should be aware of some limitations; the 2.5-liter engine could fall short for those with heavier demands. Additionally, the reduced trunk space compared to previous models may not satisfy everyone’s packing needs. Overall, the 2018 Acadia is a well-rounded choice for families desiring a capable and comfortable SUV, making it a noteworthy contender in the segment.

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.
