How much does the 2018 Buick LaCrosse cost?

Prices are up 1.83% year-over-year — a sign of continued demand for this model year.

There are 282 listings available, which suggests a modest amount of inventory for shoppers to compare.

If you find a listing below $15,797.54, 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 points to strong owner satisfaction, and the LaCrosse’s comfort-focused setup gives you a large, quiet sedan with a relaxed, upscale feel. The overview also highlights roomy seating, a larger trunk, and available features like ventilated front seats, a head-up display, wireless charging, and a partially digital instrument panel, so you get a lot of everyday comfort and convenience. If you want a traditional sedan that prioritizes calm driving and a premium atmosphere over flash, this model year fits that brief well. 24.8% 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 sedan built around comfort, quietness, and a relaxed driving character, with a standard V6 and available all-wheel drive adding to its everyday usability. It also notes that the car was designed to feel upscale and roomy, which usually matters to buyers who plan to keep a car for a while and want it to stay pleasant over time.

For used buyers, the main long-term ownership risk is making sure the car’s condition matches its premium positioning, especially if prior maintenance or wear has been uneven.

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

At 66% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can separate clean examples from cars with prior damage. After that, prioritize a thorough inspection of body panels, paint consistency, and interior condition, since those areas can reveal how well the car has been cared for. Focus on overall condition first, because a comfortable sedan like this is most appealing when it still feels refined inside and out.

What is the 2018 Buick LaCrosse's resale value?

The current average of $16,777 sits slightly above last year's $16,475.

That upward move suggests the market has held this model year in steady regard, which can help support resale confidence if you buy well. Because the price is already trending higher, a clean, well-kept example is more likely to stay attractive to future shoppers than one with visible wear or a questionable history. If you plan to sell later, condition and documentation will matter a lot in preserving value.

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:

• 24.8% of listings are priced as good or great deals.
• At 66% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices are up 1.83% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.

Consider the 2017 if:

• At $16,435, the 2017 costs less than the current year's $16,777 average.
• It marks Buick’s shift toward a more premium, modern sedan.

The bottom line: You should lean toward the 2018 if you want the stronger current-market case and are willing to shop carefully for a clean example. If your priority is saving money up front, the 2017 is the better secondary path, especially if you find one in excellent condition with a solid history.
