How much does the 2018 Buick LaCrosse cost?

Prices are up 3.78% year-over-year — a sign of continued demand for this model year.

There are 277 listings available, which gives you some room to compare condition, mileage, and equipment.

If you find a listing below $15,802.86, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2018 Buick LaCrosse a good car?

Yes — the 5/5 user rating suggests strong owner satisfaction, and the LaCrosse’s appeal centers on comfort, quietness, and a roomy, upscale cabin. The overview also points to a large sedan with a relaxed road feel, a bigger back seat, and a generous trunk, so it fits you well if you want a low-key cruiser rather than something flashy or sporty.

For shoppers who value a plush ride and a traditional sedan layout, that combination makes the LaCrosse easy to understand as a comfort-first choice. 29.2% of listings are priced as good or great deals, which gives you some market flexibility if you shop carefully.

Is the 2018 Buick LaCrosse reliable?

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

The overview suggests a car built around comfort, quietness, and a relaxed driving experience, with available all-wheel drive and a modern cabin layout. It also notes some cabin-material compromises, so you should expect the biggest ownership risk to come from finding a used example that has been maintained well and still feels solid inside.

What should I look for when buying a used 2018 Buick LaCrosse?

At 67.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

Start with a vehicle history report so you can separate clean examples from cars with collision records or repeated claims. Then prioritize a thorough pre-purchase inspection, with extra attention to body alignment, paint consistency, interior wear, and any signs that the car has been repaired after damage. Because this model is meant to feel quiet and upscale, condition matters a lot more than just the badge on the trunk.

What is the 2018 Buick LaCrosse's resale value?

The current average of $17,140 sits slightly above last year's $16,515.

That upward move suggests the market still sees value in this model year, especially for buyers who want a quiet, roomy sedan with a premium feel. If prices continue to hold near the current average, a well-kept example should remain relatively easy to position when it’s time to sell. Strong condition and desirable equipment should matter even more because shoppers in this segment tend to compare closely on comfort and presentation.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2018 Buick LaCrosse 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:

• 29.2% of listings are priced as good or great deals.
• At 67.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices are up 3.78% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2017 if:

• At $16,440, the 2017 costs less than the current year's $17,140 average.
• It marks Buick’s redesign shift toward a more premium identity.

The bottom line: If you want the stronger current-market benchmark, the 2018 is the cleaner primary target because it combines solid owner satisfaction with a still-active used market. If your priority is saving money, the 2017 is the better secondary path, especially if you find one in excellent condition and can live with the older-year pricing advantage.
