How much does the 2018 INFINITI Q50 cost?

Prices have softened 6.10% compared to this time last year, making it a favorable time to shop this model year.

There are 670 listings available, which suggests you have a reasonable amount of inventory to compare.

Is the 2018 INFINITI Q50 a good car?

Generally — the 4.47/5 user rating points to strong owner satisfaction. Drivers consistently praise its performance, features, and handling, and many specifically like the power and acceleration it delivers. The Q50 also fits well if you want a midsize premium sedan with a strong mix of equipment and value, though some owners wish it had more modern technology and a more comfortable ride. With 28.2% of listings marked as good or great deals, you have a decent chance of finding attractive pricing.

Is the 2018 INFINITI Q50 reliable?

Owners rate it 4.47/5, a solid signal of long-term satisfaction.

Owner feedback also points to a car that feels dependable in everyday use, with praise centered on performance, features, handling, and the kind of ownership experience people tend to count on over time. That said, used buyers should still plan for a careful pre-purchase check so you can reduce the risk of inheriting expensive wear or deferred maintenance.

What should I look for when buying a used 2018 INFINITI Q50?

At 47% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any damage, repairs, or title issues show up in the car’s past. Then prioritize a thorough inspection of body panels, paint consistency, tires, brakes, and suspension so you can spot signs of collision repair or hard use. Because this model is often bought for its performance and equipment, it’s smart to focus on overall condition rather than just mileage or trim level.

Is now a good time to buy a used 2018 INFINITI Q50?

This looks like a moderate, selective buyer’s market, so you can be choosy if you’re patient and compare listings carefully.

• Deal availability: 28.2% of listings are priced as good or great deals.
• Inventory: There are 670 listings available.
• Price trend: Prices have softened 6.10% compared with last year.
• Clean inventory: 47.0% of listings are accident-free.

If you find a listing below $16,072, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 INFINITI Q50's resale value?

The current average of $16,192 sits slightly below last year's $17,243.

That decline suggests the market has become a bit softer, which can work against you if you plan to sell soon. On the other hand, the lower entry price may help you buy at a more favorable point in the cycle, especially if you choose a well-kept example. Strong owner satisfaction can help support demand when it’s time to resell, particularly for shoppers who value performance and equipment.

Vehicles with solid owner satisfaction ratings, like this model year's 4.47/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2018 INFINITI Q50 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:

• 28.2% of listings are priced as good or great deals.
• At 47% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 6.10% compared with last year.
• Owners rate it 4.47/5 — a solid satisfaction signal.

The bottom line: If you want a well-equipped luxury sedan with strong owner approval and a softer current price, the 2018 is the right place to focus. If you’re especially price-sensitive, you may want to compare nearby years and shop the cleanest, best-documented example rather than chasing the lowest sticker alone.
