What is the 2018 INFINITI QX80's resale value?

The current average of $19,006 sits slightly below last year's $21,758.

That price movement suggests the market has cooled, which can make resale a little more challenging if you buy at the wrong point in the range.

Demand should remain supported by the model’s luxury features, towing ability, and strong owner satisfaction.

Vehicles with strong owner satisfaction ratings, like this model year's 4.6/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2018 INFINITI QX80 or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 33.8% of listings are priced as good or great deals.
• At 63.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 12.65% compared with last year.
• Owners rate it 4.6/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $21,244, the 2019 costs more than the current year's $19,006 average.
• It adds a more lavish, pricier feel with stronger upscale presence.

The bottom line: If you want the better value, the 2018 is the smarter primary path because it combines a lower average price with strong owner satisfaction and meaningful deal availability. If you’re willing to pay more for a slightly more upscale-feeling alternative, the 2019 is the secondary path for buyers who care less about price and more about added polish.
