Used 2018 GMC Acadia for Sale nearRichmond, VA

How much does the 2018 GMC Acadia cost?

Prices have softened 11.43% compared to this time last year, making it a favorable time to shop this model year.

There are 2,753 listings available, which suggests solid inventory for shoppers comparing trims and prices.

Is the 2018 GMC Acadia a good car?

Yes — the 2018 GMC Acadia earns a 4.8/5 user rating and a 7.2/10 expert rating. The model scores 8/10 across Form and function and Safety.

Owners consistently praise the spacious, comfortable interior, the roomy three-row layout, and the safe, family-friendly feel. The feature set also comes through as a strength, especially if you want a crossover that feels well equipped without moving all the way to the top of the lineup.

In practical terms, the Acadia makes the most sense if you want a family SUV with flexible seating and a more refined feel than a bare-bones utility vehicle. It also has a market that still shows 30.1% good and great deals, which gives you room to shop selectively.

Is the 2018 GMC Acadia reliable?

Owners rate it 4.8/5, a strong signal of long-term satisfaction.

The owner feedback points to a dependable, trouble-free ownership experience for many shoppers, with repeated praise for the Acadia’s comfortable cabin and family-friendly usability. The expert notes also frame it as a vehicle you can count on for everyday driving, especially if you choose the stronger V6 setup.

The V6’s broader availability helps reduce the risk of ending up with the underpowered four-cylinder if you need more than basic commuting duty. For used buyers, the main long-term ownership risk is choosing a poorly equipped or heavily used example that doesn’t match your needs.

What should I look for when buying a used 2018 GMC Acadia?

At 61.4% 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, alignment, and signs of prior repair. Because this model’s appeal depends heavily on trim and equipment, it’s worth checking that the features you want are actually present and functioning as expected.

Key things to evaluate:

• Trim level: The SL trim is the most basic version, with the 2.5-liter four-cylinder, front-wheel drive, a 7-inch touchscreen, Android Auto, Apple CarPlay, and a 4G LTE Wi-Fi hotspot. The SLE adds all-wheel drive availability and opens the door to the V6, while the SLE2 brings heated power front seats, a power liftgate, roof rails, and remote start. SLT trims add leather, upgraded seating, and more driver-assistance equipment, while Denali adds the most luxury content.
• Powertrain: The 2.5-liter four-cylinder makes 193 horsepower and is best suited to commuter duty. The 3.6-liter V6 makes 310 hp and is the better choice if you want towing, hauling, or stronger everyday performance. Both engines use a 6-speed transmission.
• Safety package: Driver Alert I includes blind-spot monitoring, lane-departure warning, rear cross-traffic alert, and rear parking sensors. Driver Alert II adds lane-keep assist, auto high beams, front parking sensors, and low-speed forward-collision warning with auto braking. Some of the most advanced safety tech is limited to higher trims.
• Infotainment: The base system uses a 7-inch touchscreen with Intellilink, Android Auto, Apple CarPlay, and a 4G LTE Wi-Fi hotspot. Higher trims add an 8-inch touchscreen, navigation, and virtual gauges.
• Fuel efficiency: The four-cylinder returns 21 mpg city and 26 highway. The V6 returns 17 mpg city, 25 highway, and 20 combined.

Which 2018 GMC Acadia trim should I buy?

The 2018 GMC Acadia is offered in 6 trim levels: SL, SLE, SLE1, SLE2, SLT1, SLT2.

Here's the short version:

• SL: This is the value entry point if you want the lowest price and can live with the four-cylinder and front-wheel drive. It still gives you a solid tech base, but it’s the least flexible choice for buyers who want more power or available AWD.
• SLE: This is the trim that opens up the Acadia’s broader appeal because it adds all-wheel drive availability and unlocks the V6 option. If you want the best balance of price, capability, and everyday usefulness, this is the best-value trim.
• SLE1: This trim adds LED running lights and satellite radio, making it a modest step up if you want a little more convenience and style without jumping too far in price.
• SLE2: This is the better pick if you want a more family-friendly setup, thanks to heated power front seats, a power liftgate, roof rails, remote start, and standard second-row captain’s chairs.
• SLT1: This trim is the sweet spot for many shoppers because it adds leather upholstery, upgraded front seats, a Bose stereo, and the Driver Alert I safety package.
• SLT2: Choose this if you want the most advanced mainstream equipment, including 20-inch wheels, a trailering package, heated second-row seats, and the Driver Alert II package.

The safety package content is strongest on SLT trims, and the most advanced driver-assistance features are not spread evenly across the lineup.

Is now a good time to buy a used 2018 GMC Acadia?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 30.1% of listings are priced as good or great deals.
• Inventory: There are 2,753 listings available.
• Price trend: Prices have softened 11.43% compared with last year.
• Clean inventory: 61.4% of listings are accident-free.

If you find a listing below $15,214, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 GMC Acadia's resale value?

The current average of $15,214 sits slightly below last year's $17,177.

That decline suggests the Acadia has already absorbed a meaningful amount of depreciation, which can help future sellers if prices stabilize. If you buy at the right price now, you may have less downside left than a shopper who paid closer to the prior-year average.

The model’s broad family appeal and strong owner satisfaction can help support demand when you eventually resell. Trim choice matters, though: better-equipped versions with the V6 and desirable safety features should be easier to market than a stripped-down example.

Vehicles with strong owner satisfaction ratings, like this model year's 4.8/5, tend to retain buyer demand, which supports resale value over time.

Is the 2018 GMC Acadia safe?

The Acadia earns a Top Safety Pick from IIHS when equipped with the Driver Alert II package, and it has five-star ratings in frontal collision tests and four-star ratings in all other NHTSA tests.

It earns an 8/10 safety score from our experts.

The standard safety equipment includes 4-wheel antilock disc brakes, traction and stability control, a full airbag suite, and GM’s Teen Driver technology. The Driver Alert packages add blind-spot monitoring, lane-departure warning, rear cross-traffic alert, rear parking sensors, lane-keep assist, auto high beams, front parking sensors, and low-speed forward-collision warning with auto braking.

The main caveat is that the strongest safety result depends on the right package, so you should verify the exact equipment on any used listing before you buy.

Should I buy a 2018 GMC Acadia or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 30.1% of listings are priced as good or great deals.
• At 61.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.43% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.
• The V6 is now available more broadly, which improves everyday usability and towing flexibility.

Consider the 2017 if:

• At $12,913, the 2017 costs less than the current year's $15,214 average.
• It’s the redesign year with a lighter body and a more modern feel.

Consider the 2019 if:

• At $16,942, the 2019 costs more than the current year's $15,214 average.
• It feels more upscale and distinctive, with a more refined cabin.

The bottom line: If you want the best balance of price, features, and V6 availability, the 2018 is the smart default. If your budget is tighter, the 2017 can save you money, while the 2019 is worth considering if you want a more upscale feel and can spend more.

How does the 2018 GMC Acadia compare to the 2018 Chevrolet Traverse?

Our experts score the 2018 GMC Acadia 7.2/10 and the 2018 Chevrolet Traverse 8/10.

The Traverse has the stronger overall expert score, more power, and slightly better highway fuel economy. The Acadia counters with a lower average used price, a bit more city efficiency, and a more upscale, less utilitarian feel.

If you want maximum space and stronger performance, the Traverse is the easier recommendation. If you prefer a more refined midsize SUV and want to spend a little less, the Acadia still makes a strong case.
