Used 2020 INFINITI QX80 for Sale nearSeattle, WA

How much does the 2020 INFINITI QX80 cost?

Prices have softened 15.29% compared to this time last year, making it a favorable time to shop this model year.

There are 650 listings available, which gives you a meaningful amount of inventory to compare.

Is the 2020 INFINITI QX80 a good car?

Yes — the 2020 INFINITI QX80 earns a 5/5 user rating and a 7.33/10 expert rating. The model scores 8/10 across Performance and Form and function.

It stands out as a large luxury SUV that emphasizes comfort and a premium feel, with a powerful engine and a comfortable ride as its core strengths. The trade-offs are clear, though: outdated technology and poor fuel economy hold it back.

The expert notes point to a strong powertrain and a relaxed driving character, but also call out clunky downshifts and a highway steering feel that can wander. That makes it a better fit if you value a plush cabin and easygoing cruising more than modern tech polish or sharp handling.

The market shows 33.5% good or great deals, which suggests there are still some attractive opportunities if you shop carefully.

Is the 2020 INFINITI QX80 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The QX80’s appeal comes from its straightforward, durable-feeling formula: a body-on-frame luxury SUV with a powerful V8, a comfortable ride, and a cabin built for relaxed use. The expert evaluation also points to a capable, old-school setup that prioritizes strength and comfort over complexity.

Its powertrain is described as able to handle the SUV’s weight well, and the rear auto-leveling suspension helps keep the vehicle composed and level when towing. Infiniti also backs the model with a four-year/60,000-mile basic warranty and a six-year/70,000-mile powertrain warranty.

For used buyers, the main long-term ownership risk is that age-related wear and higher operating costs can add up, especially if the vehicle has been used heavily or maintained inconsistently.

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

At 70.6% 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 thorough pre-purchase inspection, especially on a full-size SUV that may have seen family duty, towing, or long highway miles. Focus on condition, maintenance records, and signs of wear in the cabin, suspension, and drivetrain.

Key things to evaluate:

• Trim level: The QX80 is sold in two trim levels: Luxe and Limited. The cabin gets upscale materials and a refreshed exterior look, but some trim pieces still fall short of rivals, and the Limited adds matte silver and open-pore Ash wood trim.
• Powertrain: All models use a 5.6-liter V8 with a seven-speed automatic, making 400 horsepower and 413 pound-feet of torque. Rear-wheel drive is available on Luxe, four-wheel drive is available on Luxe and standard on Limited, and the SUV is notably fuel-inefficient at 14 mpg city, 20 mpg highway, 16 mpg combined in RWD form or 13 mpg city, 19 mpg highway, 15 mpg combined with 4WD.
• 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: Standard tech includes an 8-inch upper touchscreen and a 7.0-inch lower touchscreen, plus Apple CarPlay, Android Auto, navigation, satellite radio, Bluetooth, keyless entry, remote start, tri-zone climate control, and four USB ports. You can upgrade to two 8.0-inch displays, a rear-seat entertainment system, and a WiFi hot spot.
• Fuel efficiency: The EPA estimates 14 mpg city, 20 mpg highway, 16 mpg combined for rear-wheel drive and 13 mpg city, 19 mpg highway, 15 mpg combined for four-wheel drive.

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 trim to target if you want the QX80’s core strengths without jumping to the highest price point. It gives you the V8, the comfortable ride, the standard safety tech, and the full dual-screen infotainment setup, while still leaving room to add features like upgraded steering, the Theater Package, or the ProAssist Package if you want more convenience.
• Limited: Choose this if you want the most upscale version of the QX80 and are willing to pay for it. It adds a more premium presentation with matte silver and open-pore Ash wood trim, and it comes standard with four-wheel drive. It makes the most sense if you want the top-end feel and don’t mind the much higher starting price.

The standard safety equipment is strong for the class, but the available driver-assistance upgrades are worth considering if you want the most complete package.

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

This is a moderate, selective buyer’s market, so you can shop with some leverage if you stay disciplined.

• Deal availability: 33.5% of listings are priced as good or great deals.
• Inventory: There are 650 listings available.
• Price trend: Prices have softened 15.29% compared with last year.
• Clean inventory: 70.6% of listings are accident-free.

If you find a listing below $22,433, 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 $22,435 sits slightly below last year's $26,485.

That decline suggests the market has already adjusted downward, which can make the QX80 more appealing to used buyers today but less favorable for sellers trying to maximize return. If you buy at the current average or below, you may have less room for appreciation later unless the vehicle is especially clean and well equipped.

Because the model has softened meaningfully, future resale will likely depend heavily on condition, mileage, and equipment level. Well-kept examples with desirable features should hold up better than higher-mileage trucks with visible wear.

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 Infiniti QX80 earns Good scores in the moderate overlap front and side crash tests from IIHS.

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 QX80 is an older model, so it doesn’t have all the newest driver-assistance features found in some rivals. The available safety tech is solid, but you should pay close attention to which options are fitted on any used example you consider.

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:

• 33.5% of listings are priced as good or great deals.
• At 70.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 15.29% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 keeps the refreshed look, strong V8 power, and comfortable luxury-SUV character.

Consider the 2019 if:

• At $21,244, the 2019 costs less than the current year's $22,435 average.
• The 2019 is a plush, old-school luxury SUV with broad appeal.

Consider the 2021 if:

• At $29,139, the 2021 costs more than the current year's $22,435 average.
• The 2021 adds a reshuffled trim lineup and a more rugged luxury focus.

The bottom line: If you want the best balance of price and the QX80’s core strengths, the 2020 is the sensible default. If you’re shopping strictly on price, the 2019 is the better value play, while the 2021 makes sense only if you want the newer updates and are willing to pay more.
