Used 2018 Nissan Altima for SaleNationwide

How much does the 2018 Nissan Altima cost?

Prices have softened 3.07% compared to this time last year, making it a favorable time to shop this model year.

There are 2,045 listings available, which gives you a solid pool of options to compare.

Is the 2018 Nissan Altima a good car?

Yes — the 4.5/5 user rating points to strong owner satisfaction. Owners commonly praise the smooth ride, good fuel economy, and spacious trunk, while also appreciating the comfort and technology features. For you, that makes the Altima a sensible pick if you want quiet, comfortable midsize-sedan transportation with useful everyday features rather than a sporty driving feel. 29.9% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2018 Nissan Altima reliable?

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

The owner feedback also uses reliability-adjacent language around comfort, fuel economy, and everyday usability, while noting that some buyers reported trouble with maintenance and a few used-car condition issues. That means you should treat this as a model that can serve you well, but only if you verify service history and avoid neglected examples.

For used buyers, the main long-term ownership risk is buying a car with hidden maintenance or transmission-related concerns, so condition matters a lot.

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

At 47.1% 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 the car has any accident, title, or odometer issues. Then prioritize a pre-purchase inspection, with extra attention to the transmission, maintenance records, and signs of poor upkeep. Because some owner feedback mentions cleanliness and battery concerns, it also makes sense to focus on overall condition and evidence of consistent care.

Is now a good time to buy a used 2018 Nissan Altima?

This looks like a moderate, selective buyer’s market, so you can shop patiently and still find value.

• Deal availability: 29.9% of listings are priced as good or great deals.
• Inventory: There are 2,045 listings available.
• Price trend: Prices have softened 3.07% compared with last year.
• Clean inventory: 47.1% of listings are accident-free.

If you find a listing below $10,588, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Nissan Altima's resale value?

The current average of $10,813 sits slightly below last year's $11,156.

That softer pricing suggests the Altima is still a value-oriented used buy, but it also means future sellers may not see especially strong appreciation. If you buy one now, you should expect resale to depend heavily on condition, mileage, and maintenance history rather than on broad market momentum. Well-kept examples should hold up better than neglected ones because shoppers in this segment tend to reward clean, well-documented cars.

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:

• 29.9% of listings are priced as good or great deals.
• At 47.1% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 3.07% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

Consider the 2019 if:

• At $13,294, the 2019 costs more than the current year's $10,813 average.
• The 2019 brings a more modern, more competitive redesign.

The 2018 is the better path if you want a lower entry price and a value-focused midsize sedan with strong owner satisfaction. If you can spend more and want a newer-feeling alternative, the 2019 is the better upgrade. For price-sensitive buyers, the 2018 makes more sense; for shoppers prioritizing a newer design, the 2019 is worth the stretch.
