Used 2021 INFINITI QX80 for Sale nearDallas, TX

How much does the 2021 INFINITI QX80 cost?

Prices have softened 11.36% compared to this time last year, making it a favorable time to shop this model year.

There are 488 listings available, which gives you a modest amount of inventory to compare before you buy.

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, space, and a traditional truck-based feel. 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, spacious cabin, and premium interior materials. Those strengths line up with the QX80’s role as a full-size luxury SUV that prioritizes relaxed driving and a well-appointed interior.

The trade-offs are just as clear: the expert review calls out poor fuel economy and poor handling, and also notes poor value for money. That makes the QX80 a better fit if you care more about comfort and presence than efficiency or sharp road manners.

With 33.6% of listings priced as good or great deals, you have some room to shop selectively.

Is the 2021 INFINITI QX80 reliable?

The 2021 INFINITI QX80 is built around a traditional body-on-frame layout, and that old-school hardware can be a plus if you want a durable-feeling full-size SUV. Owners describe it as smooth, refined, and trouble-free in everyday use, with many appreciating its comfortable and luxurious character over the long haul.

The expert review also points to a responsive V8 and a relaxed, comfortable driving experience, which supports the sense that the QX80 is engineered for steady, dependable use rather than complexity. Infiniti’s warranty coverage includes a four-year, 60,000-mile basic warranty and a six-year, 70,000-mile powertrain warranty.

For used buyers, the main long-term risk is that a large, V8-powered luxury SUV can become expensive to own if prior maintenance was inconsistent.

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

Accident-free inventory is solid at 76.6% — always verify the vehicle history report.

You should still check the history report carefully, because a clean title alone does not tell you how well the SUV was maintained. Prioritize a thorough inspection of the suspension, brakes, electronics, and interior condition, since those are the areas where wear can show up first on a large luxury SUV. Focus on whether the cabin, tech, and bodywork still feel consistent with the QX80’s premium positioning.

Key things to evaluate:

• Trim level: The base Luxe trim rides on 20-inch wheels, while Premium Select and Sensory move to 22-inch wheels. The cabin uses leather upholstery throughout, with perforated semi-aniline leather on Sensory models, and the higher trims are the ones that feel more fully equipped.
• Powertrain: Every QX80 uses a 5.6-liter V8 with a seven-speed automatic transmission. Rear-wheel drive is standard, and four-wheel drive is available for buyers who want the added traction and low-range 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. These features are standard rather than optional, which is a strong point for the model.
• Infotainment: The standard setup uses dual touchscreens, with an 8.0-inch upper screen and a 7.0-inch lower screen. Apple CarPlay, Android Auto, a built-in WiFi hotspot, navigation, and a 13-speaker Bose audio system are standard, while a 17-speaker Bose system and rear-seat entertainment are optional.
• 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, 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 the most 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 feel, including the larger 22-inch wheels that help it look more substantial than the base model. It is the best-value choice if you want a nicer presentation without jumping all the way to the top trim.
• Sensory: This is the most luxurious version, with perforated semi-aniline leather, standard Hydraulic Body Motion Control, and the most premium overall feel. Choose it if you want the richest cabin and are willing to pay for the top-spec experience.

Standard safety equipment is already strong across the lineup, so your trim decision mostly comes down to how much luxury and visual presence you want.

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

This is a moderate market for selective buyers, so it pays to compare listings carefully and move quickly on the right one.

• Deal availability: 33.6% of listings are priced as good or great deals.
• Inventory: There are 488 listings available.
• Price trend: Prices have softened 11.36% compared with last year.
• Clean inventory: 76.6% of listings are accident-free.

If you find a listing below $29,139, 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 $29,139 sits slightly below last year's $32,874.

That decline suggests the QX80 has become more affordable for used buyers, but it also means sellers may need to price competitively to stand out. If you own one, condition and equipment level matter a lot because the market is already discounting the model.

For a future seller, the key takeaway is that the QX80’s value is being shaped by its age, fuel economy, and truck-based design. Well-kept examples should still attract buyers who want a traditional full-size luxury SUV, but you should expect pricing pressure if mileage or cosmetic wear is high.

Is the 2021 INFINITI QX80 safe?

The 2021 Infiniti QX80 earns a four-star overall 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 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. That is a strong standard list for a luxury SUV, even if the QX80’s crash-test results are not class-leading.

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:

• 33.6% of listings are priced as good or great deals.
• Accident-free inventory is solid at 76.6% — always verify the vehicle history report.
• Price trend: Prices have softened 11.36% compared with last year.
• It keeps the traditional body-on-frame formula with a comfortable ride and standard advanced safety features.

Consider the 2020 if:

• At $22,435, the 2020 costs less than the current year's $29,139 average.
• It offers luxurious comfort with a powerful engine and a relaxed driving feel.

Consider the 2022 if:

• At $36,847, the 2022 costs more than the current year's $29,139 average.
• It adds a larger 12.3-inch display and more modern tech.

The bottom line: If you want the best balance of price and the QX80’s traditional luxury-SUV character, the 2021 is the sensible pick. If your priority is saving money, the 2020 is the better value; if you want newer tech, the 2022 is the upgrade to consider.
