Used 2021 Buick Enclave for Sale nearChicago, IL

How much does the 2021 Buick Enclave cost?

Prices have softened 11.56% compared to this time last year, making it a favorable time to shop this model year.

There are 1,175 listings available, which gives you a solid pool of options to compare.

Is the 2021 Buick Enclave a good car?

Yes — the 2021 Buick Enclave earns a 5/5 user rating and a 6.33/10 expert rating. The model scores 9/10 across Look and feel and Form and function.

It stands out as Buick’s largest crossover SUV, with a roomy, quiet cabin and a stylish, upscale presentation. The trade-offs are clear, though: the interior materials can feel cheap, the technology is dated, and the value proposition is weak for the money.

The Enclave’s comfort, spaciousness, and easy-to-use technology make the strongest case for you if you want a large, refined family SUV. Its 31.7% good or great deal rate suggests there are still worthwhile listings to find if you shop carefully.

Is the 2021 Buick Enclave reliable?

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

The Enclave’s V6 powertrain and nine-speed automatic are described as smooth and well-matched, and the SUV’s ride quality is a major strength. The expert review also notes that the transmission shifts cleanly and the vehicle drives with Buick-style grace and civility.

For ownership, the main risk is less about mechanical drama and more about buying the wrong example at the wrong price, especially given the model’s weak value positioning and uneven feature availability.

What should I look for when buying a used 2021 Buick Enclave?

At 74.9% 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, paint consistency, and signs of prior repair. Because the Enclave’s safety and driver-assistance features vary by trim, you should also confirm the exact equipment on the specific listing you’re considering.

Key things to evaluate:

• Trim level: Preferred is the entry point, while Essence adds blind-spot monitoring and rear cross-traffic alert. Premium and Avenir bring the Driver Confidence Plus Package, which adds forward-collision warning with pedestrian detection, low-speed automatic emergency braking, lane-departure warning with lane-keeping assist, automatic high-beam headlights, front and rear parking sensors, and a Safety Alert Seat.
• Powertrain: Every version uses a 3.6-liter V6 with a nine-speed automatic and either front-wheel drive or all-wheel drive. The engine makes 310 horsepower and 266 pound-feet of torque, and the SUV can tow up to 5,000 pounds when properly equipped.
• Safety package: The Driver Confidence Plus Package is standard on Premium and Avenir, but not on lower trims. Adaptive cruise control with enhanced automatic emergency braking that works at highway speeds is reserved for Avenir and the optional Avenir Technology Package.
• Infotainment: The biggest screen is the Avenir’s 8-inch touchscreen. Every Enclave includes Apple CarPlay, Android Auto, SiriusXM 360L, a 4G LTE WiFi hotspot, and USB charging ports in all three rows. Wireless smartphone charging, navigation, a premium sound system, and a surround-view camera system are available.
• Fuel efficiency: The EPA rates the Enclave at 21 mpg in combined driving, and the test vehicle averaged 21.2 mpg.

Which 2021 Buick Enclave trim should I buy?

The 2021 Buick Enclave is offered in 4 trim levels: Preferred, Essence, Premium, and Avenir.

Here's the short version:

• Preferred: This is the starting point, so it makes sense if you want the Enclave’s space, V6 power, and standard smartphone integration at the lowest entry price. It is also the trim where you’ll feel the biggest feature gap versus the higher versions, especially in driver assistance.
• Essence: This is the first trim that adds blind-spot monitoring and rear cross-traffic alert, so it’s the better pick if you want a more complete safety setup without jumping all the way to the top.
• Premium: This is the best-value trim for many shoppers because it adds the Driver Confidence Plus Package, bringing forward-collision warning with pedestrian detection, lane-keeping assist, automatic high beams, parking sensors, and the Safety Alert Seat.
• Avenir: This is the most upscale version, with the strongest visual presence and the most premium cabin treatment. It also unlocks adaptive cruise control with enhanced automatic emergency braking when paired with the optional Avenir Technology Package.

The safety-package cutoff is important here: the Driver Confidence Plus Package is standard only on Premium and Avenir, while the most advanced driver-assistance setup is limited to Avenir with the optional package.

Is now a good time to buy a used 2021 Buick Enclave?

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

• Deal availability: 31.7% of listings are priced as good or great deals.
• Inventory: There are 1,175 listings available.
• Price trend: Prices have softened 11.56% compared with last year.
• Clean inventory: 74.9% of listings are accident-free.

If you find a listing below $23,346, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Buick Enclave's resale value?

The current average of $23,357 sits slightly below last year's $26,410.

That decline suggests the market has already adjusted downward, which can help you as a buyer today 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 Enclave’s broad appeal as a roomy, comfortable three-row SUV should still support demand, especially for shoppers who value space and a quiet ride. But its weaker value reputation means resale strength will depend heavily on condition, mileage, and trim.

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

Is the 2021 Buick Enclave safe?

The 2021 Buick Enclave earns five-star ratings from NHTSA overall, though frontal-impact protection rates four-star due to a four-star front passenger rating. The Insurance Institute for Highway Safety gives it high marks across the board, but a Marginal headlight performance rating keeps it from earning a Top Safety Pick accolade.

It earns a 4/10 safety score from our experts.

Buick’s Driver Confidence Plus Package includes forward-collision warning with pedestrian detection, low-speed automatic emergency braking, lane-departure warning with lane-keeping assist, automatic high-beam headlights, front and rear parking sensors, and a Safety Alert Seat. That package is standard on Premium and Avenir, while blind-spot monitoring and rear cross-traffic alert require at least Essence.

The main safety caveat is that several desirable driver-assistance features are restricted to higher trims, and the Enclave lacks some advanced systems that are increasingly common in this class.

Should I buy a 2021 Buick Enclave or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 31.7% of listings are priced as good or great deals.
• At 74.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.56% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 Enclave is praised for its roomy, quiet cabin and strong V6 performance, but it still trails on value and technology.

Consider the 2022 if:

• At $26,762, the 2022 costs more than the current year's $23,357 average.
• It adds a freshened design and standard driver-assistance technology.

The bottom line: If you want the better bargain, the 2021 is the smarter buy because pricing has softened and inventory is healthy. If you’re willing to spend more for a fresher feature set and standard safety tech, the 2022 is the better long-term pick.
