How much does the 2020 GMC Acadia cost?

Prices have softened 8.18% compared to this time last year, making it a favorable time to shop this model year.

There are 2,644 listings available, which suggests you have a solid amount of inventory to compare. If you find a listing below $20,853.49, 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.

Drivers consistently praise the smooth and quiet ride, spacious interior, and impressive features. The upscale Denali trim is also a recurring highlight, especially for its more luxurious feel. On the downside, some owners wish for better cargo space and more up-to-date technology.

That lines up with the Acadia’s use case as a family-friendly midsize SUV: it leans into comfort, space, and everyday usability more than excitement. The market still shows 32.0% 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.

The user feedback points to a vehicle people feel good about living with over time, especially because of its smooth and quiet ride, spacious interior, and impressive features. That kind of feedback usually reflects a model you can count on for daily family use and longer ownership.

The expert evaluation also emphasizes that the Acadia is comfortable, roomy, and dynamically agreeable, which supports the idea that it should be easy to live with. GMC also provides your first maintenance visit to the dealership at no charge.

For used buyers, the main long-term ownership risk is that value and equipment content may not feel as strong as the price suggests.

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

At 69.4% 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 pre-purchase inspection, especially if you’re considering a higher-mileage example or one priced near the low end of the market. Focus on condition, repair quality, and whether the equipment level matches what you expect for the trim. Because advanced safety features are not standard across the lineup, it’s worth confirming exactly what’s installed on the specific vehicle you’re considering.

Key things to evaluate:

• Trim level: The SL, SLE, SLT, AT4, and Denali trims differ meaningfully, and the base setup leaves out some advanced safety content that appears higher up the range.
• 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 use a 310-hp 3.6-liter V6.
• Safety package: Blind-spot warning and rear cross-traffic warning are standard, but 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 Acadia includes Bluetooth, Apple CarPlay, Android Auto, and GMC Connected Services with a 4G LTE WiFi hotspot; versions with an 8-inch touchscreen add 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 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 gives you the core Acadia experience, but you’ll miss out on forward collision warning and low-speed automatic emergency braking unless you move up to SLT or AT4.
• 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 tech buyers are likely to want.
• Premium/top trim: The Denali is the luxury choice, with the 310-hp 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 look and the dual-clutch AWD system, but it’s more specialized than most daily drivers need.

The safety package note to remember is that blind-spot warning and rear cross-traffic warning are standard, while more advanced driver-assistance features require an upgrade.

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

This is a moderate, selective buyer’s market, so you can shop with some leverage if you’re patient.

• Deal availability: 32.0% of listings are priced as good or great deals.
• Inventory: There are 2,644 listings available.
• Price trend: Prices have softened 8.18% compared with last year.
• Clean inventory: 69.4% of listings are accident-free.

If you find a listing below $20,853.49, 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 $20,932 sits slightly below last year's $22,796.

That price movement suggests the Acadia has already absorbed some depreciation, which can help future sellers if they buy at the right price. If you purchase near the current market average or below, you may have a better chance of limiting your loss when it’s time to sell. The model’s strong owner satisfaction also helps support demand in the used market.

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 Insurance Institute for Highway Safety gives it high marks in the tests it has completed, and the National Highway Traffic Safety Administration gives it five-star ratings in most assessments, plus a four-star rollover resistance rating.

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 the enhanced automatic emergency braking system is exclusive to Denali.

The main caveat is that advanced driver-assistance coverage is limited for a vehicle in this class, so you should verify the exact safety equipment on any used example you’re considering.

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:

• 32.0% of listings are priced as good or great deals.
• At 69.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.18% 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 $17,979, the 2019 costs less than the current year's $20,932 average.
• It offers a more athletic stance and a unique driving experience.

The bottom line: If you want the refreshed 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 live without the newer updates.
