How much does the 2020 GMC Acadia cost?

Prices have softened 8.50% compared to this time last year, making it a favorable time to shop this model year.

There are 2,660 listings available, which gives you a solid pool to compare prices and equipment. If you find a listing below $20,832.79, 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 — you’re looking at a 4.94/5 user-rated SUV with an expert rating of 7.00/10. The model scores 8/10 across Look and feel, Form and function, and Technology.

Drivers consistently praise the smooth and quiet ride, the spacious interior, and the strong feature set. The Denali trim also stands out for its upscale feel, and the cabin’s comfort makes it appealing for family trips.

The trade-offs are the high price, the limited cargo-space satisfaction some owners mention, and the fact that the value proposition can feel weak relative to what you pay. From a use-case standpoint, this is a family-friendly midsize SUV that leans more toward comfort and refinement than excitement.

With 31.4% 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 user feedback points to a dependable, trouble-free ownership experience centered on comfort, smooth operation, and a vehicle people feel good about keeping for family use. That kind of feedback matters because it suggests the Acadia can be a model you count on over time, especially if you value a quiet, easygoing SUV.

The expert evaluation also emphasizes that the Acadia is dynamically agreeable and safe based on crash testing conducted to date. GMC’s first maintenance visit at the dealership is included, which helps a little with early ownership costs.

For used buyers, the main long-term risk is less about outright durability and more about whether the vehicle’s equipment, condition, and maintenance history justify the asking price.

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

At 69.5% 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 the listing price looks unusually attractive. Focus on body condition, evidence of prior repairs, and whether the equipment level matches what you expect for the trim. Because advanced driver-assistance features are not standard across the lineup, it’s worth confirming exactly which safety systems are installed before you buy.

Key things to evaluate:

• Trim level: The base SL gives you the essentials, but it lacks forward collision warning and low-speed automatic emergency braking unless you move up. Higher trims add more premium touches, including the Denali’s wood trim and upscale presentation.
• Powertrain: Lower trims use a 193-horsepower 2.5-liter four-cylinder, the SLT gets a turbocharged 2.0-liter four-cylinder with 230 hp and 258 pound-feet of torque, and AT4 and Denali models use a 310-hp 3.6-liter V6. All versions use a nine-speed automatic.
• Safety package: Blind-spot warning and rear cross-traffic warning are standard, but forward collision warning and low-speed automatic emergency braking require at least SLT or AT4. The 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 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. Wireless charging, a high-definition surround-view camera, and a rear camera mirror are also available.
• Fuel efficiency: The test vehicle returned 21 mpg in combined driving, and the expert observed 20.1 mpg in primarily FWD use.

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:

• Base trim: The SL is the entry point, but it misses forward collision warning and low-speed automatic emergency braking, which are important safety features if you want more than the basics.
• Sweet-spot trim: The SLT is the best value pick because it adds the turbocharged 2.0-liter engine and unlocks more of the safety equipment buyers are likely to want.
• Premium/top trim: The Denali is the luxury choice, with the V6, open-pore wood trim, and the most upscale presentation in the lineup.
• Off-road trim: The AT4 is the one to choose if you want the rugged setup, but its dual-clutch AWD system and all-terrain focus make it less relevant for typical daily driving.

The safety-package note is simple: if you want the most useful driver-assistance features, you need to move beyond the base trim.

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

This is a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile deals.

• Deal availability: 31.4% of listings are priced as good or great deals.
• Inventory: There are 2,660 listings available.
• Price trend: Prices have softened 8.50% compared with last year.
• Clean inventory: 69.5% of listings are accident-free.

If you find a listing below $20,832.79, 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 $20,834 sits slightly below last year's $22,769.

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. If you shop carefully now, you may reduce the risk of taking the steepest early hit. The flip side is that a model with a weaker value reputation can be harder to command top dollar for later unless it’s well equipped and well maintained.

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?

It earns five-star ratings in most NHTSA assessments, plus a four-star rollover resistance rating. The IIHS gives the Acadia high marks in the tests it has completed.

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

The Acadia comes standard with a rear-seat reminder system, Teen Driver technology, automatic collision notification, SOS emergency calling, blind-spot warning, and rear cross-traffic warning. If you want forward collision warning and low-speed automatic emergency braking, you need to move up to SLT or AT4, and even then some features are bundled into the Driver Alert Package. That package also adds lane-departure warning, lane-keeping assistance, pedestrian braking, parking sensors, automatic high-beam headlights, and a head-up display.

The main safety caveat is that advanced driver-assistance coverage is uneven, especially on lower trims. For used buyers, that means you should verify the exact safety equipment on any listing rather than assuming it has the features you want.

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:

• 31.4% of listings are priced as good or great deals.
• At 69.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.50% compared with last year.
• Owners rate it 4.94/5 — a strong satisfaction signal.
• The 2020 refresh adds bolder styling, a new turbocharged engine, and updated technology.

Consider the 2019 if:

• At $17,684, the 2019 costs less than the current year's $20,834 average.
• It offers an upscale interior and solid driving dynamics.

The bottom line: If you want the refreshed styling, updated tech, and broader trim mix, the 2020 is the better target. If your priority is spending less up front, the 2019 is the smarter value play, especially if you can find one with the equipment and condition you want.
