How much does the 2018 BMW X3 cost?

Prices have softened 5.56% compared to this time last year, making it a favorable time to shop this model year.

There are 1,822 listings available, which suggests a healthy amount of inventory to compare.

If you find a listing below $17,374.11, 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 — it earns a 5/5 user rating and a 7.67/10 expert rating. The 2018 X3 is a fully redesigned third-generation model, and the overview makes clear that it was built to stand out in BMW’s compact-crossover lineup while still fitting the brand’s broader range. The model scores 9/10 across Form and function and Technology.

That combination makes sense if you want a compact luxury crossover that emphasizes a premium cabin, strong everyday usability, and standout tech. The market also shows 34.7% 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 overview points to a new-for-2018 redesign, which usually means you should pay close attention to how individual examples have aged and been maintained. The expert notes also highlight a smooth, well-sorted powertrain and a quiet, cushy ride, both of which support the case for solid day-to-day dependability.

BMW also includes three years or 36,000 miles of scheduled maintenance, including oil, brake fluid, air filters, and spark plugs, which helps reduce early ownership costs. For used buyers, the main long-term risk is paying for neglected maintenance or option-heavy repairs on a premium crossover.

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

At 69.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially on higher-mileage or heavily optioned examples. Focus on bodywork quality, signs of prior repair, and whether the electronics and driver-assistance features work as intended. Because this is a luxury crossover with a lot of available equipment, condition matters as much as mileage.

Key things to evaluate:

• Trim level: The standard cabin uses SensaTec vinyl, and the interior is described as conservative and tasteful rather than flashy. The available panoramic moonroof and large side glass help the cabin feel airy, but some features are reserved for higher equipment levels.
• Powertrain: The standard 2.0-liter turbocharged inline-four is described as strong, smooth, and refined, with 248 horsepower and 258 pound-feet of torque. All-wheel drive is standard, and the eight-speed automatic is praised for smooth, quick shifts.
• Safety package: Forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control are only available with two option packages. The package on the test vehicle added blind-spot monitoring and lane-departure warning.
• Infotainment: The X3 includes the latest iDrive interface and touchscreen capability, plus a 360-degree camera system, wireless device charging, Apple CarPlay, and in-car Wi-Fi. The head-up display and fast voice recognition are also standout features.
• Fuel efficiency: BMW does not provide mpg figures 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:

• Base trim: The xDrive30i gives you the core X3 experience, but some desirable safety and convenience features are still optional. Forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control require option packages, and the test vehicle’s package added blind-spot monitoring and lane-departure warning.
• Premium/top trim: The xDrive M40i adds a 3.0-liter turbocharged inline-six with 355 hp and 369 lb-ft of torque, plus upgraded brakes, a sport suspension, and a more aggressive look. If you want the strongest performance in the lineup, this is the one to target.
• Off-road trim: The X3 is tuned more for comfort than hard-edged driving, so the performance notes suggest it is best suited to everyday use rather than enthusiastic corner carving.

BMW’s safety-package setup means you should pay close attention to which driver-assistance options are included on any used example.

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

This is a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile examples.

• Deal availability: 34.7% of listings are priced as good or great deals.
• Inventory: There are 1,822 listings available.
• Price trend: Prices have softened 5.56% compared with last year.
• Clean inventory: 69.6% of listings are accident-free.

If you find a listing below $17,374.11, 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 $18,154 sits slightly below last year's $19,222.

That softer pricing suggests the market has already adjusted downward, which can help you buy at a more favorable entry point. For a future seller, that also means resale value will depend heavily on condition, mileage, and equipment rather than just model-year desirability. Well-kept examples with strong option content should hold up better than neglected 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 a 8/10 safety score from our experts.

The safety content says the 2018 X3 was too new to have been rated by NHTSA or IIHS at the time, but the previous model earned a 5-star NHTSA rating and top IIHS scores in crash and crash-prevention testing, with a Marginal headlight result that kept it from Top Safety Pick status. BMW also includes uncommon safety features such as a pre-collision system that can close the sunroof, raise the windows, and pre-tension the seat belts if a crash is imminent.

Driver-assistance features like forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control are only available with option packages, while the test vehicle’s package added blind-spot monitoring and lane-departure warning. You should verify exactly which safety features are installed on any used example, because the standard equipment set is not as comprehensive as the optioned versions.

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:

• 34.7% of listings are priced as good or great deals.
• At 69.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 5.56% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2018 model year is notable because it brought a complete overhaul, making this third-generation X3 entirely new.

The bottom line: If you want the redesigned X3 and you value the combination of strong tech, a premium cabin, and a softer used-market price, the 2018 is a smart place to focus. If you’re especially price-sensitive, you can still shop carefully and target the lower end of the range, but make sure the history and option content are right before you commit.
