Used 2020 GMC Acadia for Sale nearKansas City, MO

How much does the 2020 GMC Acadia cost?

Prices have softened 10.88% compared to this time last year, making it a favorable time to shop this model year.

There are 2,667 listings available, which suggests a healthy amount of inventory to compare.

Is the 2020 GMC Acadia a good car?

Yes — with a 4.94/5 user rating and a 7/10 expert rating, the 2020 GMC Acadia lands as a well-liked used SUV with broad appeal. The model scores 8/10 across Look and feel, Form and function, and Technology.

Owners consistently praise the smooth and quiet ride, spacious interior, and impressive features. The upscale Denali trim is especially appreciated for its luxurious feel, and many drivers also like the comfort and design for family trips.

The trade-offs are clear: advanced safety features are not standard, and performance is fairly pedestrian. That fits a three-row family SUV that emphasizes easy-to-use tech and practical packaging more than excitement.

With a roomy third row and approachable technology, it suits you best if you want a comfortable family hauler rather than a sporty crossover. The market still shows 31.7% good or great deals, so there are opportunities if you shop carefully.

Is the 2020 GMC Acadia reliable?

Owners rate it 4.94/5, a strong signal of long-term satisfaction. User feedback also points to a smooth, quiet ride and a comfortable, family-friendly cabin, which are the kinds of traits that usually support dependable day-to-day ownership.

The expert evaluation reinforces that impression with language describing the Acadia as comfortable, dynamically agreeable, and safe based on crash testing conducted to date. It also notes that GMC provides your first maintenance visit to the dealership at no charge.

For used buyers, the main long-term ownership risk is less about basic dependability and more about value, since the Acadia can feel expensive relative to the equipment you get.

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

At 68.7% 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 pre-purchase inspection, especially if you’re considering a higher-mileage example or one with a prior claim. Focus on overall condition, signs of repair quality, and whether the equipment you want is actually present on the trim you’re shopping.

Key things to evaluate:

• Trim level: The Acadia comes in SL, SLE, SLT, new rugged AT4, and luxurious Denali trim levels. Base-trim versions are more limited on premium touches, while Denali adds a more upscale look and feel with real open-pore wood trim and additional visual polish.
• Powertrain: Lower trims use a 193-horsepower 2.5-liter four-cylinder engine, SLT gets a 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, with up to 4,000 pounds of towing capacity.
• Safety package: Standard equipment includes blind-spot warning and rear cross-traffic warning, plus rear-seat reminder and Teen Driver technology. 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-beam headlights, and a head-up display.
• 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, and the model also adds USB-C ports, an optional wireless charging pad, a high-definition surround-view camera, and a rear camera mirror.
• Fuel efficiency: The test vehicle returned 21 mpg in combined driving, and the expert notes that automatic engine stop/start and cylinder deactivation are designed 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, and Denali.

Here's the short version:

• SL: This is the entry point, so it makes sense if you want the lowest-cost way into the Acadia lineup, but you’ll be giving up some of the nicer equipment and advanced safety content that appears higher up.
• SLE: This is the value-minded step up if you want the core Acadia experience without jumping too far in price. It keeps the practical family layout and easy-to-use tech that make the model appealing.
• SLT: This is the best-value trim for many shoppers because it adds the turbocharged 2.0-liter engine and unlocks more of the safety content, including forward collision warning and low-speed automatic emergency braking.
• AT4: Choose this if you want the rugged personality and the standard dual-clutch AWD system, along with all-terrain tires and the more capable setup described in the test drive.
• Denali: This is the trim to buy if you want the most upscale Acadia, with the V6, the richest cabin presentation, and the strongest luxury lean in the lineup.

The safety package is not fully standard across the lineup, so if advanced driver assistance matters to you, verify the exact equipment on the trim you’re considering.

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

This is a moderate, selective buyer’s market, so you have room to compare listings and wait for the right one.

• Deal availability: 31.7% of listings are priced as good or great deals.
• Inventory: There are 2,667 listings available.
• Price trend: Prices have softened 10.88% compared with last year.
• Clean inventory: 68.7% of listings are accident-free.

If you find a listing below $20,311, 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 $20,311 sits slightly below last year's $22,790.

That decline suggests the Acadia has softened in the used market, which can help you as a buyer but may limit upside if you plan to resell soon. If you buy at the right price, you reduce the risk of taking a bigger depreciation hit later.

The model’s broad appeal, family-friendly layout, and strong owner satisfaction can help support demand over time. Still, resale value will depend heavily on trim, condition, and whether the vehicle has accident history.

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 2020 Acadia earns five-star ratings in most NHTSA assessments, plus a four-star rollover resistance rating. The IIHS gives it high marks in other tests, though it has incomplete data because the SUV hasn’t been tested for headlight performance or for small overlap frontal-impact protection for the front passenger.

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, and the enhanced automatic emergency braking system is exclusive to Denali.

That means you should pay close attention to trim when shopping used. If safety tech matters most to you, verify the exact driver-assistance package before you buy.

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:

• 31.7% of listings are priced as good or great deals.
• At 68.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.88% compared with last year.
• Owners rate it 4.94/5 — a strong satisfaction signal.
• The 2020 refresh adds bolder styling, the AT4 trim, a turbocharged four-cylinder, a nine-speed automatic, and updated technology.

Consider the 2019 if:

• At $17,278, the 2019 costs less than the current year's $20,311 average.
• It feels more upscale than many rivals and offers a refined cabin with solid driving dynamics.

The bottom line: If you want the newer styling, updated tech, and broader trim mix, 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 can find one in strong condition with the equipment you want.
