Why it stands out
The 2018 INFINITI Q50 stands out as a midsize premium sedan that leans hard on power, equipment, and value. It was part of a long-running first generation that changed relatively little over time, and by 2018 it had already received mild styling updates, an upgraded infotainment system, and new steering wheel designs. That combination gives the car a familiar, understated look while still keeping it current enough to appeal to buyers who want a luxury sedan without chasing the newest design trends.
What makes the 2018 Q50 especially distinctive is how much it offers for the money. Standard equipment was generous even on early models, and the Q50’s trim structure included Pure, Luxe Sport, and Red Sport 400 by this point. The model also offered rear-wheel drive or all-wheel drive, and its available engines were aimed more at performance than efficiency. For buyers who value acceleration and a well-equipped cabin, that is a strong formula.
There are tradeoffs, though. Fuel economy was never a strong point, and the Q50’s long production run meant that by the end it could feel dated next to newer rivals. Still, for shoppers who want a powerful, feature-rich luxury sedan with a reputation for solid value, the 2018 INFINITI Q50 remains an appealing choice.

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.

| Year-Round Low | $16,070 |
| Year-Round High | $16,825 |

Is the 2018 INFINITI Q50 a good car?
Yes — the 2018 INFINITI Q50 earns a 4.5/5 user rating, which points to strong owner satisfaction. Drivers consistently praise its performance, features, and handling, and many specifically like the power and acceleration it delivers. The overview also frames it as a good fit if you want a powerful, well-equipped luxury sedan with solid value rather than the newest design trends. With 30.6% of listings marked as good or great deals, you have a meaningful chance to find a competitive offer.
Is the 2018 INFINITI Q50 reliable?
Owners rate it 4.5/5, a strong signal of long-term satisfaction.
The review summary also points to a car that owners feel good about living with over time, especially when it comes to dependable performance and the confidence that comes from a well-liked ownership experience. For used buyers, that suggests the bigger risk is less about broad owner dissatisfaction and more about finding a specific example that has been maintained well and still feels tight after years of use.
What should I look for when buying a used 2018 INFINITI Q50?
At 46.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should start with a vehicle history report so you can separate clean examples from cars with prior damage. After that, prioritize a thorough pre-purchase inspection, especially if the listing price looks unusually attractive. Focus on overall condition, signs of past repairs, and whether the car still feels consistent with the performance-oriented character buyers expect from this model.
Is now a good time to buy a used 2018 INFINITI Q50?
This is a moderate market, so you can be selective without expecting every listing to be a bargain.
- Deal availability: 30.6% of listings are priced as good or great deals.
- Inventory: There are 684 listings available.
- Price trend: Prices have softened 3.56% compared with last year.
- Clean inventory: 46.2% of listings are accident-free.
If you find a listing below $16,070, 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 $16,075 sits slightly below last year's $16,669.
That softer pricing suggests the model has already moved through some of its depreciation, which can help future sellers if they buy at the right price. The current market also shows enough demand to keep the car relevant, especially for shoppers who want performance and value in a premium sedan. If you maintain the car well and buy carefully, you may be better positioned to limit losses when it is time to sell.
Vehicles with strong owner satisfaction ratings, like this model year's 4.5/5, 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:
- 30.6% of listings are priced as good or great deals.
- At 46.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 3.56% compared with last year.
- Owners rate it 4.5/5 — a strong satisfaction signal.
The bottom line: The 2018 is a strong choice if you want a well-equipped luxury sedan with a favorable price trend and broad market availability. If you are especially price-sensitive, you may want to compare nearby years and focus on the cleanest, best-maintained example rather than chasing the lowest sticker price alone.
