Used 2020 INFINITI QX80 for Sale nearPhiladelphia, PA

How much does the 2020 INFINITI QX80 cost?

Prices have softened 13.77% compared to this time last year, making it a favorable time to shop this model year.

There are 671 listings available, which suggests you should have some room to compare prices and equipment.

If you find a listing below $22,938.35, 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 is positioned as the more luxurious twin to the Armada, with a focus on premium accommodations and a comfortable ride. That makes it a fit for you if you want a large SUV that prioritizes relaxed, upscale driving over cutting-edge tech.

The model scores 8/10 across Performance and Form and function.

The trade-offs are clear: the technology feels outdated, and fuel economy is poor. Even so, the QX80’s strong engine and comfortable ride give it a straightforward appeal if you value comfort and capability more than modern gadgetry.

With 29.8% of listings marked as good or great deals, you have a decent chance of finding a competitive price 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 durable, old-school formula: a body-on-frame luxury SUV with a powerful V8, a smooth ride, and a premium cabin. That combination suggests it can be a reassuring choice if you want a traditional full-size SUV experience.

Its performance notes point to a powertrain that can handle the SUV’s weight, and the ride quality is described as relatively smooth. The ownership picture is helped by 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For used buyers, the main long-term risk is that age-related wear and outdated systems may matter more than outright mechanical weakness.

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

At 69.7% 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. Focus on body condition, signs of prior repair, and whether the truck’s comfort and convenience features still work as intended. Because this is an older luxury SUV, condition matters as much as mileage.

Key things to evaluate:

• Trim level: The QX80 is offered in 2 trim levels: Luxe and Limited. Luxe gives you the core luxury-SUV experience, while Limited adds more upscale touches such as matte silver and open-pore Ash wood trim.
• Powertrain: Every QX80 uses 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 tuned more for relaxed strength than quick-shifting refinement.
• 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. You can add blind-spot monitoring, lane-departure warning, adaptive cruise control, distance-control assist, and lane-keep assist.
• Infotainment: You get an 8-inch upper touch screen and a 7.0-inch lower touch screen, plus standard Apple CarPlay, Android Auto, navigation, satellite radio, Bluetooth, and four USB ports. Two 8.0-inch displays, rear-seat entertainment, and a WiFi hot spot are available.
• Fuel efficiency: The rear-wheel-drive model is rated at 14 mpg city, 20 mpg highway, and 16 mpg combined, while the four-wheel-drive version returns 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 trim to start with if you want the QX80’s core strengths without stretching to the top price. It gives you the V8, the comfortable ride, the standard safety tech, and the main infotainment setup, so it covers the essentials well.
• Limited: Choose this if you want the more upscale presentation and are willing to pay for it. It adds richer trim details and a more premium feel, but the value case is strongest if those extras matter to you more than price.

The safety package is broad for the class, but this is still an older model, so you should pay close attention to which driver-assistance features are standard versus optional on the specific listing you’re considering.

What is the 2020 INFINITI QX80's resale value?

The current average of $22,916 sits slightly below last year's $26,574.

That drop suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For a future seller, the key question is whether the QX80’s luxury appeal and strong capability can offset its age and fuel costs. Well-kept examples should still attract shoppers who want a traditional full-size luxury SUV, but condition and equipment will matter a lot.

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 rates it good in the moderate overlap front and side crash tests, and the National Highway Traffic Safety Administration notes better crashworthiness from the side than the front, with a moderate rollover risk.

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.

Because this is an older model, you should pay close attention to which driver-assistance features are included on the exact vehicle you’re considering.

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:

• 29.8% of listings are priced as good or great deals.
• At 69.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 13.77% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 keeps the refreshed luxury look and the comfortable, powerful V8 setup.

Consider the 2019 if:

• At $21,781, the 2019 costs less than the current year's $22,916 average.
• It’s a plush, old-school luxury SUV with decent shelf appeal.

Consider the 2021 if:

• At $29,648, the 2021 costs more than the current year's $22,916 average.
• It adds a reshuffled lineup and a more rugged, old-school luxury-SUV character.

The bottom line: If you want the best balance of price and the QX80’s core strengths, the 2020 is the primary path to consider. If you’re especially price-sensitive, the 2019 can save you money while keeping the same basic formula. If you want to spend more for a newer take, the 2021 is the step-up option.
