Used 2021 INFINITI QX80 for Sale nearNew York, NY

How much does the 2021 INFINITI QX80 cost?

Prices have softened 12.23% compared to this time last year, making it a favorable time to shop this model year.

There are 503 listings available, which suggests you have a workable amount of inventory to compare.

Is the 2021 INFINITI QX80 a good car?

With a 3.8/5 user rating and an expert score of 7.3/10, the 2021 INFINITI QX80 looks strongest if you want a large luxury SUV that prioritizes comfort and presence over modern polish. The model scores 8/10 across Look and feel and Performance.

Owners commonly praise the luxurious cabin, comfortable ride, and refined interior, and they also appreciate the improved features. The expert review backs up that appeal with notes on the spacious cabin, premium interior materials, and smooth highway driving.

The trade-offs are clear: poor fuel economy and poor handling remain part of the package, and the value proposition is not especially strong. That makes the QX80 a better fit if you want a full-size luxury SUV with a rugged character and genuine capability rather than the most efficient or most modern option.

Only 33.4% of listings are priced as good or great deals, so you may need to shop carefully to find the right example.

Is the 2021 INFINITI QX80 reliable?

The 2021 INFINITI QX80’s appeal is tied to its old-school, body-on-frame design and straightforward V8 powertrain, which can be reassuring if you want a traditional full-size SUV. Owners describe it as luxurious, comfortable, and smooth, and they also point to a refined interior and improved features.

The expert review says the QX80’s V8 is very responsive, and the SUV’s construction and drivetrain are presented as part of its durable, truck-like character. The cost-effectiveness notes also mention Infiniti’s four-year, 60,000-mile basic warranty and six-year, 70,000-mile powertrain warranty.

For used buyers, the main long-term risk is that a large, heavy luxury SUV can become expensive to own if prior maintenance or wear items were neglected.

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

Accident-free inventory is solid at 75.1% — 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 that focuses on the suspension, brakes, electronics, and signs of heavy use. You should also pay close attention to cabin condition, since luxury features and interior wear can vary a lot from one example to another.

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 interior is dressed up with wood trim, contrast stitching, and standard leather upholstery, with perforated semi-aniline leather on Sensory models.
• 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 makes 400 horsepower and 413 pound-feet of torque.
• 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 8.0-inch upper and 7.0-inch lower touchscreens, with Apple CarPlay, Android Auto, a built-in WiFi hotspot, navigation, Bluetooth, SiriusXM satellite radio, and a 13-speaker Bose audio system.
• Fuel efficiency: EPA fuel-economy ratings are 16 mpg combined, 14 mpg city, and 20 mpg highway with rear-wheel drive, and 15 mpg combined, 13 mpg city, and 19 mpg highway 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, but it still 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 least expensive path into the model without giving up the essentials.
• Premium Select: This trim adds the larger 22-inch wheels and a more upscale look than Luxe, making it the middle-ground choice if you want a nicer presentation without jumping all the way to the top trim.
• Sensory: This is the best-value trim if you want the richest feature set, including perforated semi-aniline leather, 22-inch wheels, and standard Hydraulic Body Motion Control. It is the one to target if you want the most premium feel and the most complete equipment list.

Standard safety equipment is included 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 looks like a moderate, selective-buyer market, so you should shop with a clear target price and condition threshold.

• Deal availability: 33.4% of listings are priced as good or great deals.
• Inventory: There are 503 listings available.
• Price trend: Prices have softened 12.23% compared with last year.
• Clean inventory: 75.1% of listings are accident-free.

If you find a listing below $28,424, 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 $28,482 sits slightly below last year's $32,449.

That drop suggests the QX80 has already absorbed a meaningful amount of depreciation, which can help you as a buyer today. If you plan to sell later, the same trend means you should expect resale value to remain sensitive to mileage, condition, and equipment level.

Because the market has softened, a well-kept example with desirable features should be easier to move than a rough one. The best resale prospects will likely come from cleaner, better-equipped trims that still feel current to used shoppers.

Is the 2021 INFINITI QX80 safe?

The 2021 INFINITI QX80 earns a four-star overall 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 driver assistance 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 story.

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:

• 33.4% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.1% — always verify the vehicle history report.
• Price trend: Prices have softened 12.23% compared with last year.
• It adds a refreshed Smart Rearview Mirror and a reshuffled trim lineup.

Consider the 2020 if:

• At $21,791, the 2020 costs less than the current year's $28,482 average.
• It offers a more luxurious take on the Armada with premium accommodations.

Consider the 2022 if:

• At $35,787, the 2022 costs more than the current year's $28,482 average.
• It adds a widescreen 12.3-inch display with wireless Apple CarPlay and more modern tech.

The bottom line: The 2021 is the right pick if you want the updated trim structure and current-year pricing that has already softened. If your priority is saving money, the 2020 is the better value play; if you want newer tech, the 2022 is the stronger upgrade path.
