CarGurus Analysis: 2021 GMC Acadia

Summary
With 139 currently listed for sale and an average price of $22,564, 23.7% of 2021 GMC Acadia listings on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 GMC Acadia 4.86 / 5 stars.
86.3% of 2021 GMC Acadia listings on CarGurus are accident free.
Why it stands out
The 2021 GMC Acadia sits in the second generation of the model, which moved the Acadia from a full-size SUV to a midsize one. That change brought a lower MSRP, but it also meant the Acadia lost its optional eight-seat layout. For shoppers who want a used three-row crossover with a more manageable footprint than the earliest Acadias, that shift is a big part of its appeal.
For 2021, the Acadia also benefited from the updated infotainment system introduced in 2020, including Apple CarPlay and Android Auto, with available wireless smartphone compatibility added in 2021. The generation offered front- and all-wheel drive, and the available engine lineup included a 2.0-liter turbo four with 230 hp and 258 lb-ft, plus a 3.6-liter V6 rated at 310 hp and 271 lb-ft. The trim range was broad, and the All-Terrain package added rugged styling elements along with the option to remove the third row for more cargo space.
That mix of family-friendly packaging and available features makes the 2021 Acadia easy to recommend to buyers who want versatility without stepping up to a larger SUV. It is also known to be fairly reliable. On the downside, the move to midsize proportions reduced seating flexibility, and some shoppers may find the Acadia less compelling if they want maximum passenger capacity or a more performance-focused feel.

American made. Less expensive to repair. We'll appointed. Comfortable. Built to last.

We are pleased with the SLE features. Compared to our Equinox LT, it was missing heated front seats, a powered driver’s seat and lift gate. However, the 3rd row was an upgrade that we needed. The V-6 engine is also strong. We sacrificed gas mileage, but upgraded in cabin space, so it was a win for us.

The SLT meets all of my requirements and has some features that I didnt even know I was getting. A bit smaller than the Buick Enclave we traded in but we were looking to downsize a bit (we are retired and didnt need the full size car). The one draw back is the ugly front plate holder but its required in TX so you are just stuck with it.

How much does the 2021 GMC Acadia cost?
| Metric | Value |
|---|---|
| Current Average Price | $22,280 |
| Year-Round Low | $22,280 |
| Year-Round High | $25,114 |
| Average Price a Year Ago | $25,118 |
| Change vs. Last Year | −11.30% |
Prices have softened 11.30% compared to this time last year, making it a favorable time to shop this model year.
There are 1,967 listings available, which suggests solid inventory for comparison shopping.
Is the 2021 GMC Acadia a good car?
Yes — the 4.86/5 user rating points to strong owner satisfaction. Drivers commonly praise the comfortable interior, spaciousness, and the strong V-6 engine, while also appreciating the room in the third row. For you, that makes the Acadia a sensible pick if you want a family-oriented crossover with a manageable footprint and useful everyday versatility. With 34.6% of listings marked as good or great deals, there is still room to shop selectively.
Is the 2021 GMC Acadia reliable?
Owners rate it 4.86/5, a strong signal of long-term satisfaction.
The owner feedback also points to a dependable, trouble-free ownership experience, with comments that support confidence in long-term use. That said, used buyers should still expect normal wear-and-tear risk and verify how each example has been maintained.
What should I look for when buying a used 2021 GMC Acadia?
At 74.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should run a vehicle history report on any Acadia you are seriously considering and confirm whether prior damage was repaired properly. A pre-purchase inspection should focus on body condition, panel alignment, and signs of uneven wear or repair work. It also makes sense to prioritize examples with clean records and consistent maintenance, since condition can vary widely from one listing to the next.
Is now a good time to buy a used 2021 GMC Acadia?
This is a moderate market, so you can be selective without expecting every listing to be a bargain.
- Deal availability: 34.6% of listings are priced as good or great deals.
- Inventory: There are 1,967 listings available.
- Price trend: Prices have softened 11.30% compared with last year.
- Clean inventory: 74.7% of listings are accident-free.
If you find a listing below $22,280, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2021 GMC Acadia's resale value?
The current average of $22,280 sits slightly below last year's $25,118.
That price movement suggests the Acadia has already absorbed some depreciation, which can help future sellers if the market stabilizes. If you buy at a competitive price and keep the vehicle in strong condition, you may have a better chance of limiting your loss later. Demand should also benefit from the model's strong owner satisfaction and family-friendly appeal.
Vehicles with strong owner satisfaction ratings, like this model year's 4.86/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2021 GMC Acadia or consider a different year?
If you're weighing the 2021 against nearby model years, here's how to think about it:
Choose the 2021 if:
- 34.6% of listings are priced as good or great deals.
- At 74.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 11.30% compared with last year.
- Owners rate it 4.86/5 — a strong satisfaction signal.
Consider the 2020 if:
- At $20,007, the 2020 costs less than the current year's $22,280 average.
- It adds bolder styling and more distinctive trim choices.
The bottom line: If you want the better-balanced mix of owner satisfaction, modern features, and current-market pricing, the 2021 is the stronger default choice. If your priority is spending less up front, the 2020 is the better value path, especially if you find one in clean condition with the equipment you want.
