How much does the 2018 BMW X3 cost?

Prices have softened 6.76% compared to this time last year, making it a favorable time to shop this model year.

There are 1,787 listings available, which gives you a solid pool of options to compare.

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 version that feels new even if its shape is familiar. It’s aimed at you if you want a premium compact crossover that blends everyday usefulness with a refined, tech-forward cabin and a strong sense of polish.

36.1% of listings are priced as good or great deals, which suggests there are still some attractive opportunities in the market.

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 well-built, South Carolina-made crossover with smart engineering touches and a strong emphasis on comfort and refinement. Its turbocharged four-cylinder is praised for pulling hard with little vibration, and the eight-speed automatic is described as exceptionally smooth. BMW also includes three years or 36,000 miles of scheduled maintenance, which helps reduce early ownership friction.

The main long-term ownership risk for used buyers is that premium-brand upkeep and option-package complexity can make repairs and maintenance more expensive than you might expect.

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

At 68.7% 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 careful pre-purchase inspection, especially if the listing has any accident history or a long option list. Pay close attention to how the cabin electronics, cameras, and driver-assistance features operate, since this model leans heavily on technology. It’s also worth checking that the ride, brakes, and transmission feel smooth in normal driving, because this X3 is tuned more for comfort than for aggressive handling.

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 it feel airy. Higher equipment levels add features such as bi-LED headlights and the 360-degree camera system, so base-trim listings may leave out some of the more desirable convenience and visibility upgrades.
• Powertrain: The standard 2.0-liter turbocharged inline-four is rated at 248 horsepower and 258 pound-feet of torque, and BMW’s eight-speed automatic is described as smooth and responsive. All-wheel drive is standard, and the former rear-wheel-drive version is no longer offered.
• Safety package: Forward-collision alert, automatic emergency 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, but it does not include lane centering.
• Infotainment: The X3 includes the latest iDrive interface, touchscreen capability, in-car Wi-Fi, wireless device charging, Apple CarPlay, a 360-degree camera system, and a head-up display. The system also supports fast voice dictation and recognition for navigation.
• Fuel efficiency: BMW includes three years or 36,000 miles of scheduled maintenance, including oil, brake fluid, air filters, and spark plugs.

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 to focus on if you want the core X3 experience with the standard turbocharged four-cylinder, standard all-wheel drive, and the model’s strongest blend of comfort, refinement, and everyday usability. It’s the best-value choice for most shoppers because it delivers the redesign and the key luxury features without stepping into the higher-priced performance model.
• xDrive M40i: This version 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. Choose it if you want the quickest and most performance-focused X3 in this lineup.

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, with enough inventory to shop carefully and enough pricing softness to create opportunities.

• Deal availability: 36.1% of listings are priced as good or great deals.
• Inventory: There are 1,787 listings available.
• Price trend: Prices have softened 6.76% compared with last year.
• Clean inventory: 68.7% 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 $17,896 sits slightly below last year's $19,194.

That decline suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For a future seller, it also means your resale outcome will depend heavily on condition, mileage, and equipment rather than on broad market appreciation. Well-kept examples with desirable features should hold up better than rougher, less-equipped listings.

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 offers driver-assistance features through the Driving Assistance and Driving Assistance Plus packages, including forward-collision alert, automatic emergency braking with pedestrian detection, adaptive cruise control, blind-spot monitoring, and lane-departure warning. The car also includes 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. One caveat is that the X3 will not center itself in the lane like vehicles with some semi-autonomous systems.

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:

• 36.1% of listings are priced as good or great deals.
• At 68.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 6.76% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2018 model year is notable for being a complete overhaul, so you get the third-generation X3’s fresh redesign and updated tech.

The bottom line: If you want the newest-feeling version of this generation and you’re shopping with a value-conscious mindset, the 2018 is the right place to start. If your priority is broader year-to-year comparison shopping, you may also want to look at nearby model years for differences in price, equipment, and condition, especially if you’re trying to maximize value on a used luxury crossover.
