How much does the 2018 BMW X3 cost?

Prices have softened 7.87% compared to this time last year, making it a favorable time to shop this model year.

There are 1,857 listings available, which gives you a solid pool of options to compare.

Is the 2018 BMW X3 a good car?

Yes — 5/5 from users and 7.7/10 from our experts. The 2018 X3 is a complete overhaul for the year, and BMW’s approach keeps it familiar in size and shape while making it thoroughly new underneath. It fits well if you want a compact luxury crossover that blends everyday usefulness with a premium feel and a fresh-generation design.

The model scores 9/10 across Form and function and Technology.

The X3’s market position is also healthy, with 36.2% of listings marked as good or great deals.

Is the 2018 BMW X3 reliable?

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

BMW describes the X3 as a thoroughly new third-generation model, and the expert review highlights a strong turbocharged four-cylinder, a smooth 8-speed automatic, and standard all-wheel drive. It also notes three years or 36,000 miles of scheduled maintenance, which helps reduce early ownership friction.

For used buyers, the main long-term risk is paying luxury-car maintenance and repair costs once the included maintenance period ends.

What should I look for when buying a used 2018 BMW X3?

At 68.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report before you commit, then prioritize a pre-purchase inspection that checks bodywork, electronics, and any signs of prior collision repair. Focus on condition and equipment level, since this model’s tech and option packages can materially change the ownership experience.

Key things to evaluate:

• Trim level: The X3’s cabin is conservative and tasteful, with standard SensaTec upholstery, a panoramic moonroof, and large side glass that make it feel airy. Higher equipment levels add features such as bi-LED headlights and the 360-degree camera system, while the base setup leaves some desirable convenience and tech items for pricier packages.
• Powertrain: The 2.0-liter turbocharged inline four makes 248 horsepower and 258 pound-feet of torque, and the 8-speed automatic is described as smooth and responsive. All-wheel drive is standard, and BMW also offers a more powerful 3.0-liter turbocharged inline six in the M40i.
• Safety package: BMW’s driver-assistance features include forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control, but those are only available with option packages. The car can also be equipped with blind-spot monitoring and lane-departure warning, and it does not center itself in the lane.
• Infotainment: The X3 includes the latest iDrive interface, touchscreen capability, in-car Wi-Fi, wireless device charging, Apple CarPlay, and a 360-degree camera system on higher equipment. It also offers fast voice dictation and recognition, plus a head-up display.
• Fuel efficiency: No fuel-economy figure is stated in the available data.

Which 2018 BMW X3 trim should I buy?

The 2018 BMW X3 is offered in 2 trim levels: xDrive30i, xDrive M40i.

Here's the short version:

• xDrive30i: This is the trim most shoppers should start with because it delivers the core X3 experience: a strong turbo four-cylinder, standard all-wheel drive, smooth shifting, and the upscale cabin and tech that define the model. It’s the best-value choice if you want the X3’s main strengths without paying for the more powerful six-cylinder.
• xDrive M40i: Choose this if you want the more powerful 3.0-liter turbocharged inline six, along with upgraded brakes, a sport suspension, and a more aggressive look. It’s the right pick if performance matters more to you than value.

BMW’s safety and driver-assistance features are split across option packages, so check carefully for the equipment you want before you buy.

Is now a good time to buy a used 2018 BMW X3?

This is a moderate market for selective buyers, with enough inventory and deal activity to make comparison shopping worthwhile.

• Deal availability: 36.2% of listings are priced as good or great deals.
• Inventory: There are 1,857 listings available.
• Price trend: Prices have softened 7.87% compared with last year.
• Clean inventory: 68.3% of listings are accident-free.

If you find a listing below $17,368, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 BMW X3's resale value?

The current average of $17,488 sits slightly below last year's $18,982.

That price movement suggests the market has already adjusted downward, which can help future resale if you buy at the right number today. If you keep mileage reasonable and maintain the vehicle well, you’ll be starting from a more favorable entry point than a year ago.

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

Is the 2018 BMW X3 safe?

The 2018 X3 is still too new to have been rated by the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS). However, the previous 2017 X3 scored a five-star NHTSA rating and top scores in all IIHS crash and crash-prevention tests, with only a Marginal for headlight performance.

It earns an 8/10 safety score from our experts.

BMW’s driver-assistance suite includes forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control, but those features are only available with two option packages. The X3 can also be equipped with blind-spot monitoring and lane-departure warning, though lane centering is not part of the setup.

Should I buy a 2018 BMW X3 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:

• 36.2% of listings are priced as good or great deals.
• At 68.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.87% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2018 model year stands out because it received a complete overhaul, giving the X3 a fresh start with a thoroughly new third-generation design.

The bottom line: If you want the newest-feeling version of this generation and you’re comfortable shopping carefully for condition and equipment, the 2018 is the right path. If your priority is stretching your budget, a later-year alternative may offer similar appeal, but the 2018 still makes sense when you find a well-kept example at the right price.

How does the 2018 BMW X3 compare to the 2018 Audi Q5?

Our experts score the 2018 BMW X3 7.7/10 and the 2018 Audi Q5 7.8/10. The X3 brings a stronger used-price value and more listings, while the Q5 edges it on expert score and deal share. The BMW also has the higher accident-free share, which may matter if you want a cleaner pool of listings to choose from.
