Used 2020 GMC Acadia for Sale near New York

How much does the 2020 GMC Acadia cost?

Prices have softened 10.63% compared to this time last year, making it a favorable time to shop this model year.

With 2,680 listings available, you have a solid amount of inventory to compare across trims and conditions.

If you find a listing below $20,397.96, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 GMC Acadia a good car?

Yes — the 2020 GMC Acadia earns a 4.94/5 user rating and a 7.00/10 expert rating. The model scores 8/10 across Look and feel, Form and function, and Technology.

Owners consistently praise the smooth and quiet ride, the spacious interior, and the impressive features. The upscale Denali trim is especially well liked for its more luxurious feel, and the Acadia’s family-trip comfort comes through clearly in the feedback.

The trade-offs are just as clear: the price can feel high, cargo space could be better, and the technology updates do not fully erase the sense that this SUV is still a bit vanilla. Even so, the Acadia’s practical three-row layout and easy-to-use tech make it a strong fit if you want comfort and usability more than flash.

With 31.0% of listings marked as good or great deals, you have room to shop selectively.

Is the 2020 GMC Acadia reliable?

Owners rate it 4.94/5, a strong signal of long-term satisfaction.

The owner feedback also points to a dependable, trouble-free ownership experience, with drivers repeatedly highlighting comfort and confidence over the long haul. That kind of praise matters if you want a used SUV you can count on for family duty.

The expert evaluation also emphasizes that the Acadia is safe based on crash testing to date and that its infotainment is easy to live with, which supports the sense that it is built for steady everyday use. GMC also includes the first maintenance visit at no charge, which is a small but welcome ownership perk.

For used buyers, the main long-term risk is less about outright durability and more about whether you’re comfortable with the Acadia’s value equation and its limited standard driver-assistance coverage.

What should I look for when buying a used 2020 GMC Acadia?

At 68.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a careful inspection of bodywork, panel alignment, and signs of prior repair. Because the Acadia’s appeal depends heavily on comfort and family usability, condition matters a lot more than a small cosmetic bargain.

Pay close attention to how the cabin, infotainment, and safety equipment function in real-world use. If you’re shopping a higher-mileage example, make sure the SUV still feels tight, quiet, and well maintained.

Key things to evaluate:

• Trim level: The Acadia comes in SL, SLE, SLT, new rugged AT4, and luxurious Denali trim levels. Base trims are more basic in feel, while Denali adds leather upholstery, real open-pore wood trim, and more upscale visual touches. The AT4 is the rugged-looking choice, but the content also makes clear that the Denali is the most premium-feeling version.
• Powertrain: Lower trims use a 193-horsepower 2.5-liter four-cylinder, SLT gets a new turbocharged 2.0-liter four-cylinder with 230 hp and 258 pound-feet of torque, and AT4 and Denali use a 310-hp 3.6-liter V6. The V6 and nine-speed automatic are described as smooth and refined, while the turbo four is the newer efficiency-minded option.
• Safety package: The base Acadia SL and up include blind-spot warning and rear cross-traffic warning. Forward collision warning and low-speed automatic emergency braking require SLT or AT4 at minimum, and the broader Driver Alert Package adds lane-departure warning, lane-keeping assistance, pedestrian braking, parking sensors, automatic high beams, and a head-up display. Enhanced automatic emergency braking is exclusive to Denali.
• Infotainment: Every 2020 Acadia includes Bluetooth, Apple CarPlay, Android Auto, and GMC Connected Services with a 4G LTE WiFi hotspot. Versions with an 8-inch touchscreen get a higher-resolution display, a simplified interface, and improved voice recognition.
• Fuel efficiency: The test vehicle returned 21 mpg in combined driving, and the expert notes that stop/start and cylinder deactivation are used to improve fuel economy.

Which 2020 GMC Acadia trim should I buy?

The 2020 GMC Acadia is offered in 5 trim levels: SL, SLE, SLT, AT4, Denali.

Here's the short version:

• SL: This is the entry point, and it gives you the Acadia’s core three-row practicality plus standard blind-spot warning and rear cross-traffic warning. It makes sense if you want the lowest-cost way into the model, but you should expect to pay extra for more advanced driver assistance.
• SLE: This trim keeps the Acadia’s family-friendly layout and easy-to-use tech while moving you beyond the most basic setup. It is the sensible step-up choice if you want a little more equipment without chasing luxury trim pricing.
• SLT: This is the best-value trim for many shoppers because it unlocks the new turbocharged 2.0-liter engine and also makes forward collision warning and low-speed automatic emergency braking available. If you want the strongest balance of equipment and everyday usefulness, this is the trim to focus on.
• AT4: Choose this if you want the rugged personality and the standard dual-clutch AWD system, all-terrain tires, and blacked-out appearance. It also gets the V6, so it suits buyers who want a more distinctive look and stronger capability.
• Denali: This is the luxury pick, with the V6, upscale interior touches, and the exclusive enhanced automatic emergency braking system. It is the right choice if you want the most premium Acadia experience and are willing to pay for it.

Safety-package note: forward collision warning and low-speed automatic emergency braking are not standard on the base SL and require at least SLT or AT4.

Is now a good time to buy a used 2020 GMC Acadia?

This looks like a moderate, selective buyer’s market, so you can shop carefully without feeling rushed.

• Deal availability: 31.0% of listings are priced as good or great deals.
• Inventory: There are 2,680 listings available.
• Price trend: Prices have softened 10.63% compared with last year.
• Clean inventory: 68.4% of listings are accident-free.

If you find a listing below $20,397.96, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 GMC Acadia's resale value?

The current average of $20,392 sits slightly below last year's $22,817.

That price movement suggests the Acadia has already absorbed a meaningful amount of depreciation, which can help future sellers if they buy at the right price today. A softer market now can also mean less downside risk later if you avoid overpaying.

The model’s broad appeal as a comfortable, family-friendly three-row SUV should help support demand, especially for well-kept examples with desirable equipment. Strong condition and a clean history will matter a lot if you want to protect resale value.

Vehicles with strong owner satisfaction ratings, like this model year's 4.94/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 GMC Acadia safe?

The National Highway Traffic Safety Administration gives the 2020 Acadia five-star ratings in most assessments, plus a four-star rollover resistance rating. The Insurance Institute for Highway Safety gives the SUV high marks in the tests it has completed, though some evaluations were not performed.

It earns a 6/10 safety score from our experts.

Standard safety equipment includes a rear-seat reminder system, Teen Driver technology, automatic collision notification, SOS emergency calling, blind-spot warning, and rear cross-traffic warning. Forward collision warning and low-speed automatic emergency braking require SLT or AT4 at minimum, while the Driver Alert Package adds lane-departure warning, lane-keeping assistance, pedestrian braking, parking sensors, automatic high beams, and a head-up display.

The main caveat is that advanced driver-assistance coverage is limited unless you move up the trim ladder, and the enhanced automatic emergency braking system is reserved for Denali.

Should I buy a 2020 GMC Acadia or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 31.0% of listings are priced as good or great deals.
• At 68.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.63% compared with last year.
• Owners rate it 4.94/5 — a strong satisfaction signal.
• The 2020 refresh adds bolder styling, a new AT4 trim, a turbocharged four-cylinder, a nine-speed automatic, and updated technology.

Consider the 2019 if:

• At $17,390, the 2019 costs less than the current year's $20,392 average.
• It feels more upscale than many rivals while still delivering solid driving dynamics.

The bottom line: If you want the refreshed styling, updated tech, and broader trim and powertrain choices, the 2020 is the better all-around pick. If your priority is spending less up front, the 2019 is the smarter value play, especially if you find a clean example with the right equipment.
