The Old QX80 Now Delivering Escalade Feel for CX-90 Money

The current full-size luxury SUV landscape presents a striking financial reality. Heavy depreciation takes its biggest toll on secondary-tier luxury nameplates. While iconic badges, such as the Mercedes-Benz G-Class, retain high resale premiums on the used market, equally capable body-on-frame competitors experience steep value drops within their first five to eight years of service.
For buyers shopping in the $20,000 to $35,000 price range, this dynamic creates an interesting cross-shopping scenario. That budget typically covers a brand-new midsize unibody crossover in its entry-to-mid trims or a fully sorted, late-model full-size luxury SUV equipped with a naturally aspirated V8 engine, standard body-on-frame architecture, and expansive three-row proportions.
The Full-Size Luxury Contender Makes A Strong Case For Buying Used
Recent Depreciation Is Working In The Buyer’s Favor

New vehicle pricing across the three-row family SUV segment has climbed steadily. A new 2026 Mazda CX-90 carries a base starting MSRP of $39,300, with popular mid-tier trims like the 3.3 Turbo Premium Sport climbing past $47,000. Similarly, a new midsize Infiniti QX60 easily commands $50,000 to $60,000 depending on drive system and options.
On the pre-owned market, initial owners absorb the bulk of a vehicle’s financial depreciation during its first four years. Market listing data from CarGurus shows that the second-generation full-size Japanese luxury SUVs from model years 2018 through 2021 now average between $18,700 and $28,800. This places pre-owned full-size capability directly below or on par with the starting price of new unibody crossovers.
The Flagship That Offers Escalade Presence Without Escalade Penalties

When buyers seek maximum interior scale and highway presence, the Cadillac Escalade ESV serves as an industry benchmark. However, pre-owned Escalades come with specific trade-offs. Older fourth-generation Escalade ESVs (2015-2020) command around $25,000 to $31,000 on average for high-mileage examples, but air suspension components and GM eight-speed/10-speed automatic transmissions present known long-term service items. Fifth-generation Escalades (2021+) remain high on the price curve, hovering above $52,000.
Choosing a lesser-discussed Japanese body-on-frame SUV delivers a similar physical footprint, measuring over 208 inches in length and 79 inches in width, along with standard body-on-frame durability, while dodging the premium price tag attached to the Cadillac badge.

The V8 Platform Behind The QX80 — And Why It’s Built To Outlast Depreciation

The vehicle delivering this value proposition is the second-generation, major-facelift 2018-2024 Infiniti QX80. Built on Nissan’s heavy-duty Y62 global platform, which also underpins the rugged Nissan Patrol, the QX80 uses traditional body-on-frame construction designed for severe-duty global markets.
Under the hood sits the naturally aspirated 5.6-liter VK56VD V8 engine, generating 400 horsepower and 413 pound-feet of torque, mated to a JATCO seven-speed heavy-duty automatic transmission. The engine features direct injection and Variable Valve Event and Lift (VVEL).

Independent durability data backs the platform’s reputation. RepairPal rates the Infiniti QX80 at 3.5 out of 5.0 for reliability, placing it above average for full-size luxury SUVs where complex air suspensions and electronics frequently inflate ownership costs. Long-term study data from iSeeCars routinely ranks the underlying Y62 platform among the top long-lasting vehicles capable of reaching 200,000 to 250,000+ miles with standard maintenance.
Sweet-Spot Value Math: 2018-2021 Vs. 2022-2024 Models

The second-generation Infiniti QX80, introduced in 2018, marked a significant exterior redesign, replacing the rounded front fascia of the earlier QX80/QX56 with a squared-off hood, raised LED headlights, and modern grille geometry. This ultimately created two distinct value tiers on the pre-owned market. On one hand, 2018-2021 models serve as the depreciation sweet spot, with CarGurus listing data averaging $18,700 to $21,000 for 2018-2019 examples and $22,400 to $28,800 for 2020-2021 versions, giving buyers the fully updated body styling and heavy-duty V8 drivetrain while retaining the older dual-screen InTouch cabin layout.
On the other hand, 2022-2024 models command higher prices, with 2022 QX80s averaging $36,400 and 2023-2024s reaching up to $45,100. While these later models introduce an upgraded tech-forward single 12.3-inch infotainment display with wireless Apple CarPlay, they trade away a substantial portion of the steep pre-owned discount that makes the platform such a compelling value proposition.
Living With It: Space, Towing, And Real-World Usability

Inside, the QX80 provides genuine full-size passenger packaging. Second-row captain’s chairs or a split-bench seat offer 41.0 inches of legroom, while the third row provides 28.8 inches of legroom with power-reclining seat backs fitted as standard. With all seats folded flat, overall cargo capacity reaches 95.1 cubic feet. Sound insulation is exceptional, thanks to thick acoustic glass and extensive frame dampening inherited from its flagship position.
V8 Power And Towing Capacity Make Up For Gas-Pump Reality

The primary trade-off of the QX80 is fuel consumption. The EPA rates the 5.6-liter V8 4WD models at 13 MPG City / 19 MPG Highway / 15 MPG Combined. Real-world combined fuel economy generally settles between 14 and 16 MPG depending on driving style and payload. Premium fuel is recommended for optimal output.
In exchange for higher fuel usage, the QX80 delivers utility that unibody midsize crossovers cannot match. Standard equipment includes an integrated Class IV tow hitch and rear automatic self-leveling suspension, enabling an 8,500-pound maximum towing capacity. By comparison, a Mazda CX-90 tops out at 3,500 to 5,000 pounds, depending on trim.
What To Look For And Who This SUV Makes Sense For
Common Points To Inspect Before Buying

When shopping for a pre-owned 2018-2024 Infiniti QX80, targeted inspection steps are essential to ensure long-term reliability and avoid costly repairs. Buyers should pay close attention to model-specific hardware, starting with the optional Hydraulic Body Motion Control (HBMC) system on higher Sensory trims; its fluid-based anti-roll connections should be checked for weeping leaks, whereas standard steel-coil setups with rear self-leveling air shocks offer simpler maintenance.
On the powertrain side, listen closely for ticking noises during a cold start, which can signal hairline cracks in the exhaust manifolds, a known service item on high-mileage VK56 engines. Additionally, verify that the rear air-leveling compressor cycles smoothly without excessive noise when weight is added to the rear bumper, and cross-reference the vehicle’s VIN on the NHTSA database to confirm all dealer recalls, including fuel pump replacements on select model years, have been completed.
The Final Verdict On A Full-Size Flagship

The 2018-2024 Infiniti QX80 represents an ideal pre-owned choice for specific buyers who value body-on-frame durability, V8 towing power, and expansive cabin scale over high fuel economy or giant digital dashboard displays.
The Infiniti QX80 is ideally suited for value hunters seeking sub-$30,000 pricing who prioritize broad-shouldered V8 highway power, standard 8,000+ pound towing capacity, and expansive cabin space — and is not ideally suited for drivers needing a small, easily maneuverable footprint or high fuel efficiency above 25 MPG, long daily city commuters facing steep gas bills, or tech enthusiasts who insist on ultra-modern touchscreens and digital interfaces.

Purchasing a vehicle is ultimately an exercise in prioritizing trade-offs. A new midsize crossover brings pristine bumper-to-bumper warranty coverage, updated driver-assistance software, and lower monthly fuel bills.
However, for buyers who want true flagship scale, genuine multi-ton towing capability, and a proven 400-horsepower V8 drivetrain, a pre-owned 2018-2021 Infiniti QX80 offers significant value. By letting the first owner absorb the steep initial depreciation, smart secondary market buyers can acquire full-size luxury presence for mainstream money.
