How much does the 2018 BMW X3 cost?

Prices have softened 7.10% compared to this time last year, making it a favorable time to shop this model year.

There are 1,808 listings available, which gives you a solid amount of inventory to compare before you buy.

Is the 2018 BMW X3 a good car?

Yes — it earns a 5/5 user rating and a 7.67/10 expert rating. The model scores 9/10 across Form and function and Technology.

The 2018 X3 is a complete redesign for the year, so you’re looking at a third-generation model that feels fresh even if its shape is familiar. It’s aimed at you if you want a premium compact crossover that emphasizes refinement, strong everyday usability, and a well-executed tech package rather than flashy styling.

The market also shows 35.6% of listings as good or great deals, which gives you some room to shop selectively.

Is the 2018 BMW X3 reliable?

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

The X3 is presented as a polished, well-built luxury crossover with a quiet cabin, smooth power delivery, and a comfortable ride. Its standard all-wheel drive and strong turbocharged engine help it feel composed in daily use, while BMW’s three years or 36,000 miles of scheduled maintenance adds some ownership support early on.

BMW’s own maintenance coverage helps reduce some early service burden, but used buyers should still watch for the usual premium-brand ownership costs as the miles add up.

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

At 68.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially if you’re comparing multiple listings at similar prices. Focus on condition, equipment, and whether the car has the option packages you want, since some desirable features were bundled rather than standard.

Key things to evaluate:

• Trim level: The cabin is conservative and tasteful, with standard SensaTec upholstery, a panoramic moonroof, and large side glass that make the X3 feel airy. Higher equipment levels add more luxury and convenience, so you should pay close attention to feature gaps if you’re shopping a lower-spec example.
• Powertrain: The standard 2.0-liter turbocharged inline-four is rated at 248 horsepower and 258 pound-feet of torque, while the M40i uses a 3.0-liter turbocharged inline-six with 355 hp and 369 lb-ft of torque. The eight-speed automatic is described as smooth and responsive, and all-wheel drive is standard.
• Safety package: Forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control are only available with the Driving Assistance and Driving Assistance Plus packages. A separate Driving Assistance package adds blind-spot monitoring and lane-departure warning, so check carefully for those features if they matter to you.
• Infotainment: The X3 includes the latest iDrive interface, touchscreen capability, a 360-degree camera system, wireless device charging, Apple CarPlay, in-car Wi-Fi, and a head-up display. The 360-degree camera system is tied to the highest “Executive Tier,” so verify whether a listing has it before assuming it’s included.
• Fuel efficiency: BMW does not state an MPG figure here.

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 buyers should start with because it delivers the core X3 experience: strong turbo-four performance, standard all-wheel drive, a smooth eight-speed automatic, and the roomy, upscale cabin that defines the model. It’s the best-value choice if you want the redesigned X3 without paying for the more powerful six-cylinder.
• xDrive M40i: Choose this if you want the more powerful 3.0-liter turbocharged inline-six, upgraded brakes, a sport suspension, and a more aggressive character. It’s the right pick if you care more about performance than value.

Driver-assistance features such as forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control are only available with the Driving Assistance and Driving Assistance Plus packages.

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

This is a moderate market for selective buyers, so you can shop carefully and still find worthwhile listings.

• Deal availability: 35.6% of listings are priced as good or great deals.
• Inventory: There are 1,808 listings available.
• Price trend: Prices have softened 7.10% compared with last year.
• Clean inventory: 68.9% 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 $17,871 sits slightly below last year's $19,237.

That price movement suggests the market has cooled, which can help you as a buyer today but may limit upside if you plan to sell soon. If you buy at the right price and keep the vehicle in strong condition, you’ll be better positioned to protect value later. The X3’s premium-brand appeal and broad shopper interest should still support demand over time.

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).

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

BMW includes a driver-assistance suite with forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control, but those features are only available with the Driving Assistance and Driving Assistance Plus packages. A separate Driving Assistance package adds blind-spot monitoring and lane-departure warning. The X3 also includes uncommon safety features such as a pre-collision system that can shut the sunroof, windows, and pre-tension the seat belts if it detects an imminent crash, plus automatic post-crash braking and door unlocking.

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:

• 35.6% of listings are priced as good or great deals.
• At 68.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.10% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2018 X3 is a complete overhaul for the year, so you’re getting the redesigned third-generation model rather than the older version.

The bottom line: If you want the newer-generation X3 with a fresh redesign, strong tech, and a premium feel, the 2018 is the better path. If you’re mainly shopping for the lowest possible price, a nearby year may be worth comparing, but the 2018’s redesign and softened pricing make it the more compelling choice for many used buyers.
