How much does the 2018 Nissan Altima cost?

Prices have softened 8.49% compared to this time last year, making it a favorable time to shop this model year.

There are 1,992 listings available, which suggests you have a solid amount of inventory to compare.

If you find a listing below $10,615.50, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2018 Nissan Altima a good car?

Yes — owners give it 4.5/5, which points to strong overall satisfaction.

The review summary highlights performance, comfort, and technology features as recurring strengths. It also calls out the smooth ride, good fuel economy, and spacious trunk as reasons many owners like it.

That lines up well with the model's role as a practical midsize sedan for families and commuters, especially if you want a roomy, easygoing daily driver with useful features. With 26.6% of listings marked as good or great deals, you still have room to shop selectively.

Is the 2018 Nissan Altima reliable?

Owners rate it 4.5/5, a strong signal of long-term satisfaction.

The review summary also points to a car that many owners find dependable in day-to-day use, with praise for its smooth ride and good fuel economy supporting that impression. At the same time, some owners mention maintenance-related concerns, so you should pay close attention to service history and how the car has been cared for.

For used buyers, that means long-term ownership risk is manageable if you choose carefully, but it rises quickly when maintenance records are thin or warning signs are ignored.

What should I look for when buying a used 2018 Nissan Altima?

At 49.7% 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 reported damage was minor or structural. Then prioritize a pre-purchase inspection so you can check for mechanical issues, signs of poor repairs, and maintenance gaps.

Because some owners mention transmission and battery concerns, focus on how the car drives, shifts, and starts, and make condition your main filter rather than price alone.

What is the 2018 Nissan Altima's resale value?

The current average of $10,670 sits slightly below last year's $11,660.

That decline suggests the market has been willing to pay less for this model year, which can limit upside if you plan to sell in the near future. If you buy at a strong price, you may reduce the impact of future depreciation, but a softer market usually means you should not expect a quick rebound.

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 Nissan Altima 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:

• 26.6% of listings are priced as good or great deals.
• At 49.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.49% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $13,829, the 2019 costs more than the current year's $10,670 average.
• It adds a bolder redesign with upgraded tech and a more modern cabin.

The bottom line: If you want the lower entry price and are willing to inspect carefully, the 2018 is the better value play. If you want a newer-feeling Altima and can stretch your budget, the 2019 is the stronger upgrade path; price-sensitive buyers should stay focused on the 2018 and target the best-maintained examples.
