CarGurus Analysis: 2018 INFINITI Q50

Summary
With 668 currently listed for sale and an average price of $16,194, 27.4% of 2018 INFINITI Q50s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 INFINITI Q50 4.47 / 5 stars.
46.4% of 2018 Q50 models on CarGurus are accident free.
Why it stands out
The 2018 INFINITI Q50 stands out as a midsize premium sedan that leans on a strong mix of power, equipment, and value. It was part of a long-running first generation that changed relatively little over time, and by 2018 it had received mild styling updates, an upgraded infotainment system, and new steering wheel designs. That combination gives the car a familiar, understated look with enough modernized detail to keep it competitive.
What makes the 2018 Q50 especially appealing is how much it offered for the money. Standard equipment was generous, and even early entry-level models came with automatic LED headlights, dual-zone climate control, remote keyless entry, eight-way power driver’s seat adjustment, SiriusXM satellite radio, 17-inch aluminum-alloy wheels, voice recognition, and a rear-view camera. Premium trim and above added heated front seats, a Bose premium audio system, and Infiniti InTouch, while driver-assistance safety features were available from the start, though initially as options. Owners also tend to praise the car’s performance, features, and handling, with many highlighting its power and acceleration.
There are tradeoffs, though. The Q50’s fuel economy was never a strong point, and the model range was limited compared with many rivals. By the end of its run it was also starting to feel dated, and some owners note that the ride could be more comfortable. Even so, for buyers who want a well-equipped luxury sedan with strong performance and a competitive price, the 2018 INFINITI Q50 has a clear appeal.

The features on the vehicle are amazing, I really love the sporty look. And it is worth every penny, I honestly don’t think I would’ve found a better one for such a great price.

Highly recommend this car! We were looking to purchase either the Kia Stinger GT2, Genesis G70 or the Q50 Red Sport. Never got to drive a G70 due to limited stock, but got to test drive the Kia Stinger and compared to the Q50 it wasnt even close. The Q50 has much better rideability, more refined, quieter and faster. We are looking forward to enjoying this plush sleeper for many years.

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.
