How much does the 2018 Buick LaCrosse cost?

Prices are up 1.38% year-over-year — a sign of continued demand for this model year.

If you find a listing below $15,797.47, 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 2018 Buick LaCrosse earns a 5/5 user rating, which points to strong owner satisfaction.

The overview describes it as a large, quiet sedan that prioritizes comfort over flash, with a roomy cabin, a larger trunk, and available upscale features. It also highlights a relaxed, upscale driving feel and a traditional Buick sedan character, which makes it a fit if you want comfort, space, and a low-key personality rather than sporty handling.

30.5% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2018 Buick LaCrosse reliable?

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

The overview points to a comfort-focused sedan with a standard V6, available all-wheel drive, and a straightforward upscale mission, which generally supports confidence for everyday use. It also notes some cabin-material compromises, so you should expect a used example to feel more about comfort and value than premium craftsmanship.

For used buyers, the main long-term ownership risk is making sure the car you choose has been maintained well enough to preserve its quiet, comfortable character.

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

At 65.6% 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 prior damage was repaired properly. Put inspection priority on body alignment, paint consistency, and signs of uneven wear, then focus on overall condition inside the cabin since the overview notes some flimsy plastic parts. A careful test drive should also help you judge whether the car still feels quiet, smooth, and well sorted.

What is the 2018 Buick LaCrosse's resale value?

The current average of $16,536 sits slightly above last year's $16,310.

That modest increase suggests the market has held up reasonably well, which is a positive sign if you plan to sell later. The year-over-year gain is not dramatic, but it does show that demand has stayed steady enough to support values. For a future seller, that means a clean, well-kept example should remain easier to move than a neglected one.

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:

• 30.5% of listings are priced as good or great deals.
• At 65.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices are up 1.38% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2017 if:

• At $16,258, the 2017 costs less than the current year's $16,536 average.
• It marks Buick’s shift toward a more premium, modern sedan.

The bottom line: If you want the stronger current-market case, the 2018 is the better primary target because it combines solid owner satisfaction with a still-reasonable price and meaningful deal availability. If you’re more price-sensitive, the 2017 is worth a look because it costs less and still delivers the LaCrosse’s core premium-sedan appeal.
