How much does the 2018 BMW X3 cost?

Prices have softened 6.32% compared to this time last year, making it a favorable time to shop this model year.

There are 1,822 listings available, which gives you a solid amount of inventory to compare before you buy.

If you find a listing below $17,377, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2018 BMW X3 a good car?

Yes — the 2018 BMW X3 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 redesign makes this third-generation X3 entirely new, and it keeps BMW’s compact-crossover formula focused on a premium feel, strong packaging, and a cabin that aims to stand apart in a crowded segment. The overview and test-drive notes point to a vehicle that balances everyday usefulness with BMW’s usual emphasis on distinction, while the tech and space scores back up that practical side.

28.2% of listings are priced as good or great deals, so you have some room to shop selectively.

Is the 2018 BMW X3 reliable?

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

The 2018 X3 is described as a thoroughly updated model with a strong powertrain and a well-executed automatic transmission, and the test-drive notes also point to smooth operation, quiet cruising, and a composed ride. BMW’s included scheduled maintenance for three years or 36,000 miles helps soften early ownership costs, which is useful on a luxury crossover like this.

For used buyers, the main long-term risk is that premium parts and option-heavy examples can make upkeep more expensive once the included maintenance period ends.

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

At 69.8% 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 the listing has any accident history or a long option list. Pay close attention to how the electronics, driver-assistance features, and transmission behave, since this model leans heavily on technology and refinement. It also makes sense to confirm that any expensive packages or camera systems actually work as advertised.

Key things to evaluate:

• Trim level: The cabin comes standard with SensaTec vinyl, while leather and upscale lighting details help separate better-equipped examples from more basic ones. The highest equipment tier adds the bi-LED headlights and the 360-degree camera system, so base and mid-level cars can feel meaningfully less loaded.
• Powertrain: The standard 2.0-liter turbocharged inline-four is rated at 248 horsepower and 258 pound-feet of torque, and the xDrive M40i uses a 3.0-liter turbocharged inline-six with 355 hp and 369 lb-ft of torque. All-wheel drive is standard, and the eight-speed automatic is a major strength.
• 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. The car you’re shopping may have blind-spot monitoring and lane-departure warning from the Driving Assistance package, but not the full suite.
• Infotainment: The X3 includes the latest iDrive interface, touchscreen capability, a 360-degree camera system on higher equipment, wireless device charging, Apple CarPlay, in-car Wi-Fi, and fast voice dictation and recognition. The head-up display and camera integration are standout features worth checking carefully.
• Fuel efficiency: No mpg or MPGe figure is stated in the provided 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 better-value choice if you want the core X3 experience without paying for the more powerful six-cylinder setup. It gives you the standard turbocharged four-cylinder, standard AWD, and the same strong tech foundation, so it should suit most shoppers best.
• xDrive M40i: This is the pick if you want the stronger 3.0-liter turbo six, upgraded brakes, a sport suspension, and a more aggressive character. It makes sense if performance matters more to you than value.

The safety package is split across option groups, so make sure the specific car you’re considering has the driver-assistance features you want.

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

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 28.2% of listings are priced as good or great deals.
• Inventory: There are 1,822 listings available.
• Price trend: Prices have softened 6.32% compared with last year.
• Clean inventory: 69.8% of listings are accident-free.

If you find a listing below $17,377, 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 $18,012 sits slightly below last year's $19,226.

That decline suggests the market has already adjusted downward, which can help you buy more confidently now but may also limit short-term upside if you plan to resell soon. For a future seller, the key is to buy well and avoid overpaying, because a softer market can compress your margin later. Well-equipped examples with strong condition and clean history should still be easier to move than neglected or accident-damaged ones.

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?

It earns top scores in all IIHS crash and crash-prevention tests, but only a Marginal for headlight performance, which keeps it from becoming a Top Safety Pick.

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

BMW’s driver-assistance setup includes forward-collision alert, auto braking with pedestrian detection, adaptive cruise control, blind-spot monitoring, and lane-departure warning, depending on package selection. The car also adds uncommon safety features such as a pre-collision system that can close the sunroof and windows, tighten the seat belts, disable the battery, apply the brakes, and unlock the doors after a crash.

The main caveat is the headlight-performance weakness, and some of the most desirable active-safety features are not standard.

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:

• 28.2% of listings are priced as good or great deals.
• At 69.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 6.32% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2018 model year is notable because it received a complete overhaul, making this third-generation X3 entirely new.

The bottom line: If you want the newest-feeling version of this generation and you value the updated design, tech, and packaging, the 2018 is the right place to start. If you’re mainly chasing the lowest purchase price, a nearby older year may be easier on your budget, but you’ll give up the full redesign and some of the newer equipment.
