Used 2018 Nissan Altima for Sale near Ontario

How much does the 2018 Nissan Altima cost?

Prices have softened 16.03% compared to this time last year, making it a favourable time to shop this model year.

There are 78 listings available, which suggests a reasonable amount of inventory to compare before you buy.

Is the 2018 Nissan Altima a good car?

Yes — the 2018 Nissan Altima earns a 4.5/5 user rating, which points to strong owner satisfaction. Owners commonly praise its comfort, smooth ride, good fuel economy, and technology features, and the spacious trunk adds to its everyday usefulness. For you, that makes it a sensible fit if you want a comfortable, feature-rich midsize sedan with standard all-wheel drive in Canada. With 25.6% of listings marked as good or great deals, there is still 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 points to a car that many people find dependable and trouble-free in day-to-day use, especially when it comes to comfort and routine commuting. At the same time, some reviews mention transmission concerns and maintenance-related issues, so used buyers should pay close attention to service history and overall condition. For long-term ownership, the biggest risk is buying a poorly maintained example rather than the model itself.

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

This looks like a moderate, selective buyer’s market, so you can afford to compare listings carefully rather than rush.

• Deal availability: 25.6% of listings are priced as good or great deals.
• Inventory: There are 78 listings available.
• Price trend: Prices have softened 16.03% compared with last year.

If you find a listing below $11,924 CAD, 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 $12,139 CAD sits slightly below last year's $14,457 CAD.

That gap suggests the market has already adjusted downward, which can make the car easier to buy now but less favourable if you are thinking about future resale. If you own one for a few years, the softer pricing trend may limit how much value it holds compared with a stronger-performing segment. Even so, a well-kept example can still appeal to shoppers looking for comfort, standard AWD, and a strong equipment list.

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:

• 25.6% of listings are priced as good or great deals.
• Price trend: Prices have softened 16.03% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

The bottom line: If you want a comfortable, well-equipped midsize sedan with standard all-wheel drive and you value a lower entry price, the 2018 is the one to focus on. If you are especially price-sensitive, you can also compare nearby years to see whether a similar car is listed at a better number, but the 2018 already looks attractive for shoppers who want value and a strong feature set.
