Used 2021 INFINITI QX80 for Sale near Massachusetts

How much does the 2021 INFINITI QX80 cost?

Prices have softened 11.10% compared to this time last year, making it a favorable time to shop this model year.

There are 492 listings available, which gives you a modest amount of inventory to compare.

Is the 2021 INFINITI QX80 a good car?

The 2021 INFINITI QX80 is a mixed but appealing choice if you want a large luxury SUV that leans into comfort and traditional SUV character. It earns a 3.8/5 user rating and a 7.33/10 expert rating.

The model scores 8/10 across Look and feel and Performance.

Owners commonly praise the comfortable ride, premium interior materials, and spacious cabin. The review feedback also points to a refined interior and a generally smooth driving experience, which fits the QX80’s upscale, relaxed personality.

The trade-offs are just as clear: experts call out poor fuel economy and poor handling, and owners note concerns about value for money and missing entertainment features in lower trims. That makes it a better fit if you care more about comfort, space, and a traditional luxury-SUV feel than efficiency or sharp road manners.

With 35.4% of listings marked as good or great deals, there’s enough market activity to shop selectively.

Is the 2021 INFINITI QX80 reliable?

The 2021 INFINITI QX80 is built around a traditional body-on-frame layout, which supports its long-haul, truck-based character. Owners describe it as reliable, comfortable, and trouble-free in everyday use, with a refined interior and a smooth driving experience that help it feel dependable over time.

The expert evaluation also emphasizes its comfortable ride and quiet cabin, both of which support relaxed ownership. Infiniti’s warranty coverage includes a four-year, 60,000-mile basic warranty and a six-year, 70,000-mile powertrain warranty, which adds some reassurance for used buyers.

Even so, a used QX80 can still carry the usual long-term ownership risks of a large, complex luxury SUV, so condition and maintenance history matter a lot.

What should I look for when buying a used 2021 INFINITI QX80?

Accident-free inventory is solid at 77.2% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not guarantee a clean individual vehicle. Prioritize a pre-purchase inspection, especially on higher-mileage examples or trucks with signs of heavy family use. Focus on cabin condition, electronics, and evidence of regular maintenance, since luxury features and age-related wear can affect ownership costs.

Key things to evaluate:

• Trim level: The base Luxe trim rides on 20-inch wheels, while Premium Select and Sensory models get 22-inch wheels. The cabin uses standard leather upholstery, but Sensory models upgrade to perforated semi-aniline leather. Lower trims may leave you wanting more equipment, especially if you expect a more fully loaded luxury experience.
• Powertrain: All models use a 5.6-liter V8 with a seven-speed automatic transmission. Rear-wheel drive is standard, and four-wheel drive is available. The engine is responsive and makes 400 horsepower and 413 pound-feet of torque, but the transmission can feel less smooth than you might expect.
• Safety package: Standard equipment includes adaptive cruise control, blind-spot monitoring, lane-departure warning, lane-keep assist, forward collision warning, automatic emergency braking with pedestrian detection, and Backup Collision Intervention. These features are standard rather than optional, which is a plus for lower trims.
• Infotainment: The standard setup uses dual touchscreens measuring 8.0 inches and 7.0 inches, plus Apple CarPlay, Android Auto, a built-in WiFi hotspot, navigation, Bluetooth, SiriusXM satellite radio, and a 13-speaker Bose audio system. The interface can be frustrating to use, so test it yourself before you buy.
• Fuel efficiency: EPA ratings are 16 mpg combined with rear-wheel drive and 15 mpg combined with four-wheel drive. That’s a weak point, so factor fuel costs into your budget.

Which 2021 INFINITI QX80 trim should I buy?

The 2021 INFINITI QX80 is offered in 3 trim levels: Luxe, Premium Select, and Sensory.

Here's the short version:

• Luxe: This is the entry point, and it gives you the core QX80 experience with standard leather upholstery, the dual-screen infotainment setup, and the full suite of standard driver-assistance features. It makes sense if you want the QX80’s comfort and capability without paying for extras you may not need.
• Premium Select: This trim adds a more upscale look and 22-inch wheels, making it the better middle-ground choice if you want a richer appearance without jumping to the top model.
• Sensory: This is the best-value pick if you want the most luxurious version of the QX80, since it adds perforated semi-aniline leather, 22-inch wheels, and standard Hydraulic Body Motion Control. It suits you best if you want the most comfort and the most polished feel.

Standard safety features are included across the lineup, so you do not need to move up a trim just to get the core driver-assistance package.

Is now a good time to buy a used 2021 INFINITI QX80?

This is a moderate market for selective buyers, with enough inventory and pricing movement to make comparison shopping worthwhile.

• Deal availability: 35.4% of listings are priced as good or great deals.
• Inventory: There are 492 listings available.
• Price trend: Prices have softened 11.10% compared with last year.
• Clean inventory: 77.2% of listings are accident-free.

If you find a listing below $29,331, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 INFINITI QX80's resale value?

The current average of $29,332 sits slightly below last year's $32,996.

That decline suggests the QX80 has softened in the market, which can help you as a buyer today. For a future seller, it means you should expect resale value to depend heavily on condition, mileage, and equipment rather than on broad market momentum.

Because the current average is still close to the year-round low, well-priced examples may move faster than higher-priced listings. If you buy carefully now and keep the vehicle in strong condition, you may be better positioned when it is time to sell.

Is the 2021 INFINITI QX80 safe?

The 2021 INFINITI QX80 earns a four-star overall safety rating from NHTSA, with five-star ratings in side crash tests, four-star ratings in frontal crash tests, and a three-star rollover rating.

It earns a 7/10 safety score from our experts.

Standard safety features include adaptive cruise control, blind-spot monitoring, lane-departure warning, lane-keep assist, forward collision warning, automatic emergency braking with pedestrian detection, and Backup Collision Intervention. That is a strong standard list for the class, especially since Infiniti makes these features standard equipment rather than reserving them for higher trims.

The main caveat is the three-star rollover result, which is worth keeping in mind if safety is a top priority for you.

Should I buy a 2021 INFINITI QX80 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:

• 35.4% of listings are priced as good or great deals.
• Accident-free inventory is solid at 77.2% — always verify the vehicle history report.
• Price trend: Prices have softened 11.10% compared with last year.
• It keeps the traditional body-on-frame luxury-SUV feel while adding small updates for the year.

Consider the 2020 if:

• At $22,601, the 2020 costs less than the current year's $29,332 average.
• It emphasizes comfort and premium feel with a more clearly differentiated luxury identity.

Consider the 2022 if:

• At $36,659, the 2022 costs more than the current year's $29,332 average.
• It adds a larger display and more modern tech features.

The bottom line: If you want the best balance of price, inventory, and the QX80’s classic luxury-SUV character, the 2021 is the sensible default. If your budget is tighter, the 2020 is the value play; if you want newer tech and can spend more, the 2022 is the upgrade path.
