How much does the 2020 INFINITI QX80 cost?

If you find a listing below $22,764.25, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 INFINITI QX80 a good car?

Yes — 5/5 from owners and 7.33/10 from expert testing. The QX80’s appeal is its large-SUV comfort, premium feel, and strong capability, especially if you want relaxed, upscale driving over flashier tech. The expert testing also points to a powerful engine and a comfortable ride as its core strengths.

The trade-offs are clear: outdated technology and poor fuel economy. That means you should expect a vehicle that leans into traditional luxury and easygoing road manners rather than modern gadgetry or efficiency.

32.2% of listings are priced as good or great deals, which gives you a decent chance to find a competitive offer.

Is the 2020 INFINITI QX80 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction. The QX80’s reliability story is tied to its straightforward, old-school layout and its emphasis on comfort and capability rather than complexity. Expert testing also notes that the powertrain handles the SUV’s weight well and that the ride stays composed and smooth.

The ownership picture is helped by 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 age and heavy use can magnify maintenance and wear costs on a large, premium SUV.

What should I look for when buying a used 2020 INFINITI QX80?

At 68.4% 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 pre-purchase inspection, especially on a full-size SUV that may have seen family hauling, towing, or long-distance use. Focus on condition details that matter most in a luxury truck-based SUV: ride quality, steering feel, interior wear, and evidence of uneven maintenance.

Key things to evaluate:

• Trim level: The QX80 is sold in just two trim levels: Luxe and Limited. The cabin is generally attractive and uses soft-touch materials, but some trim pieces are not up to the standard of other SUVs in this class. Limited-grade models add matte silver and open-pore Ash wood trim.
• Powertrain: Every QX80 uses a 5.6-liter V8 with a seven-speed automatic and 400 horsepower plus 413 pound-feet of torque. Rear-wheel drive is available on Luxe, four-wheel drive is available on Luxe, and Limited comes standard with 4WD. The SUV is capable on sand, mud, slippery climbs, and dirt trails, but highway stability can be a weak point.
• Safety package: Standard equipment includes automatic emergency braking, rear cross-traffic alert, pedestrian detection, forward collision warning, rear parking sensors, a surround-view camera system, and automatic collision notification. Available upgrades include blind-spot monitoring, lane-departure warning, adaptive cruise control, distance-control assist, and lane-keep assist.
• Infotainment: You get an 8-inch upper screen and a 7.0-inch lower screen, plus Apple CarPlay, Android Auto, navigation, satellite radio, Bluetooth, keyless entry, remote start, tri-zone climate control, and four USB ports. Buyers can upgrade to two 8.0-inch displays, a rear-seat entertainment system, and a WiFi hot spot.
• Fuel efficiency: The rear-wheel-drive model is rated at 14 mpg city, 20 mpg highway, and 16 mpg combined. The four-wheel-drive model is rated at 13 mpg city, 19 mpg highway, and 15 mpg combined.

Which 2020 INFINITI QX80 trim should I buy?

The 2020 INFINITI QX80 is offered in 2 trim levels: Luxe and Limited.

Here's the short version:

• Luxe: This is the value play if you want the QX80’s core strengths without jumping to the pricier top trim. You still get the V8, the dual-screen infotainment setup, and the standard safety equipment, so it covers the essentials well.
• Limited: This is the better choice if you want the most upscale version of the QX80 and are willing to pay for it. It adds more premium trim treatment and comes standard with 4WD, making it the more fully equipped option.

The safety package is broad for the class, but this is still an older SUV, so you should verify which driver-assistance features are actually present on the specific vehicle you’re considering.

Is now a good time to buy a used 2020 INFINITI QX80?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find opportunities.

• Deal availability: 32.2% of listings are priced as good or great deals.
• Inventory: There are 665 listings available.
• Price trend: Prices have softened 13.66% compared with last year.
• Clean inventory: 68.4% of listings are accident-free.

If you find a listing below $22,764.25, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 INFINITI QX80's resale value?

The current average of $22,763 sits slightly below last year's $26,364.

That price movement suggests the market has already adjusted downward, which can help future resale buyers but may limit upside for a seller in the near term. If you buy now, you’re entering at a lower average price than last year, which can reduce the amount of depreciation you absorb from today’s market level. A well-kept example should still be easier to move than one with visible wear or a rough history.

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 2020 INFINITI QX80 safe?

The Insurance Institute for Highway Safety (IIHS) has earned the QX80 good scores in the moderate overlap front and side crash tests.

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

Standard safety features include automatic emergency braking, rear cross-traffic alert, pedestrian detection, forward collision warning, rear parking sensors, a surround-view camera system, and automatic collision notification. You can add blind-spot monitoring, lane-departure warning, adaptive cruise control, distance-control assist, and lane-keep assist.

The safety picture is solid for an older luxury SUV, but you should keep in mind that it does not have the newest driver-assistance breadth found in newer rivals.

Should I buy a 2020 INFINITI QX80 or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 32.2% of listings are priced as good or great deals.
• At 68.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 13.66% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 QX80 emphasizes luxurious accommodations and a refreshed face while keeping its traditional capability.

Consider the 2019 if:

• At $21,452, the 2019 costs less than the current year's $22,763 average.
• It is a plush, old-school luxury SUV that still moves in decent numbers.

Consider the 2021 if:

• At $29,557, the 2021 costs more than the current year's $22,763 average.
• It adds an improved Smart Rearview Mirror and a reshuffled trim lineup.

The bottom line: If you want the best balance of price, comfort, and traditional full-size SUV capability, the 2020 is the sensible target. If you’re shopping on a tighter budget, the 2019 can save you money, while the 2021 makes sense only if you want the newer updates and are willing to pay more.
