Used 2021 INFINITI QX80 for Sale nearPhoenix, AZ

How much does the 2021 INFINITI QX80 cost?

Prices have softened 11.83% compared to this time last year, making it a favorable time to shop this model year.

There are 497 listings available, which gives you a modest amount of inventory to compare before you buy.

Is the 2021 INFINITI QX80 a good car?

With a 3.8/5 user rating and a 7.33/10 expert rating, the 2021 INFINITI QX80 lands as a solid but selective buy rather than a universal crowd-pleaser. The model scores 8/10 across Look and feel and Performance.

Owners consistently praise the comfortable ride, spacious cabin, and premium interior materials. The review summary also points to a luxurious feel and a smooth driving experience, which fits the QX80’s role as a full-size luxury SUV built for relaxed cruising.

The trade-offs are clear: the expert review calls out poor fuel economy, poor handling, and poor value for money. That means you should view it as a comfort-first, traditional luxury SUV rather than a sharp-handling or efficiency-focused choice.

If you want a large SUV with a premium cabin and a more rugged, truck-based character, the QX80 fits that brief well. If you care more about efficiency or modern driving dynamics, you may want to keep shopping.

Only 34.6% of listings are priced as good or great deals, so you’ll want to compare carefully before jumping on the first appealing example.

Is the 2021 INFINITI QX80 reliable?

The 2021 INFINITI QX80 is built around a traditional body-on-frame layout, and owners describe it as reliable, comfortable, and smooth in everyday use. The review summary also suggests a refined and trouble-free ownership experience for many shoppers, especially those focused on long-term comfort rather than cutting-edge tech.

Its V8 powertrain is described as responsive, and the SUV’s independent suspension helps deliver a composed ride that supports long-distance use. Infiniti also includes a four-year, 60,000-mile basic warranty and a six-year, 70,000-mile powertrain warranty, which adds some peace of mind for used buyers.

For a used purchase, the main long-term risk is that a large, older luxury SUV can become expensive if prior maintenance was skipped or wear items were neglected.

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

Accident-free inventory is solid at 76.9% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not replace a proper records review. Prioritize a pre-purchase inspection, especially on a full-size luxury SUV where suspension, electronics, and wear items can add up. Focus on overall condition, since cosmetic issues and missing equipment can matter more than they would on a simpler vehicle.

Key things to evaluate:

• Trim level: The base Luxe trim rides on 20-inch wheels, while Premium Select and Sensory get 22-inch wheels. The cabin uses standard leather upholstery, but Sensory adds perforated semi-aniline leather, so lower trims may feel less upscale.
• 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 for added capability.
• 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.
• Infotainment: The standard setup uses dual touchscreens, with an 8.0-inch upper display and a 7.0-inch lower display. Apple CarPlay, Android Auto, a built-in WiFi hotspot, navigation, Bluetooth, SiriusXM satellite radio, and a 13-speaker Bose audio system are standard.
• Fuel efficiency: EPA ratings are 16 mpg combined with rear-wheel drive and 15 mpg combined with four-wheel drive.

Which 2021 INFINITI QX80 trim should I buy?

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

Here's the short version:

• Luxe: This is the entry point, and it gives you the core QX80 experience with the standard V8, leather upholstery, dual-screen infotainment, and the full suite of standard driver-assistance features. It makes sense if you want the lowest starting price and are comfortable skipping the extra visual and comfort upgrades.
• Premium Select: This trim adds a more upscale look and feel, including the larger 22-inch wheels. It’s the best-value choice if you want a noticeable step up from the base model without going all the way to the top trim.
• Sensory: This is the most luxurious version, with perforated semi-aniline leather, 22-inch wheels, and the strongest feature set in the lineup. It suits you best if you want the richest cabin and don’t mind paying more for it.

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

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

This is a moderate market for selective buyers, with enough inventory and price movement to reward careful shopping.

• Deal availability: 34.6% of listings are priced as good or great deals.
• Inventory: There are 497 listings available.
• Price trend: Prices have softened 11.83% compared with last year.
• Clean inventory: 76.9% of listings are accident-free.

If you find a listing below $29,378, 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 $29,390 sits slightly below last year's $33,334.

That decline suggests the QX80 has become more affordable for used buyers, but it also means sellers may face softer pricing than they would have a year ago. If you own one, your resale value will likely depend heavily on condition, mileage, and equipment level.

For future sellers, the current trend points to a market that is still willing to pay for a well-kept example, but not at the same level it did last year. A clean, well-optioned QX80 should hold up better than a neglected one, especially if it has desirable features and a strong service history.

Is the 2021 INFINITI QX80 safe?

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

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

Standard safety 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. Those features are standard rather than trim-dependent, which helps the QX80’s safety case.

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:

• 34.6% of listings are priced as good or great deals.
• Accident-free inventory is solid at 76.9% — always verify the vehicle history report.
• Price trend: Prices have softened 11.83% compared with last year.
• It adds a refreshed mirror and a reshuffled trim lineup.

Consider the 2020 if:

• At $22,760, the 2020 costs less than the current year's $29,390 average.
• It emphasizes comfort and premium feel over efficiency.

Consider the 2022 if:

• At $36,743, the 2022 costs more than the current year's $29,390 average.
• It adds a larger display and more modern tech.

The bottom line: The 2021 is the right pick if you want the traditional QX80 formula at a softer price than newer models. If you’re especially price-sensitive, the 2020 is the value play; if you want newer tech, the 2022 is the upgrade path.
