How much does the 2018 BMW X3 cost?

Prices have softened 6.58% compared to this time last year, making it a favorable time to shop this model year.

There are 1,762 listings available, which gives you a solid amount of inventory 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 rather than a carryover. The overview frames it as a premium compact crossover for buyers who want a fresh redesign from a luxury brand in a crowded segment, and the expert review emphasizes its conservative, tasteful design, airy cabin, and strong tech execution.

The market also shows 34.2% of listings priced as good or great deals, which suggests there are still worthwhile opportunities if you shop carefully.

Is the 2018 BMW X3 reliable?

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

The expert review points to a well-built cabin, a smooth-shifting 8-speed automatic, and a turbocharged four-cylinder that feels stronger than its size suggests. It also notes that BMW includes three years or 36,000 miles of scheduled maintenance, which helps soften early ownership costs.

For used buyers, the main long-term risk is that premium-brand upkeep can still be expensive once routine coverage ends, so condition and service history matter a lot.

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

At 68.8% 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 or repair history. Focus on the condition of the electronics, cameras, driver-assistance features, and any signs of uneven wear that could point to harder use or deferred maintenance.

Key things to evaluate:

• Trim level: The cabin uses standard SensaTec vinyl, and the interior is described as conservative and tasteful with a panoramic moonroof and large side glass that make it feel airy. Higher equipment levels add more upscale convenience and tech, so base-trim shoppers should pay close attention to which comfort and visibility features are actually included.
• Powertrain: The standard 2.0-liter turbocharged inline four is rated at 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 the former rear-wheel-drive version is no longer available.
• Safety package: Forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control are only available with two option packages. A separate package adds blind-spot monitoring and lane-departure warning, while the car does not center itself in the lane like some semi-autonomous systems.
• 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 review also highlights fast voice dictation and recognition, plus a display that can show the car as it appears outside when using the surround-view system.
• Fuel efficiency: No fuel-economy 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 trim to start with if you want the core X3 experience at the lower entry price. It uses the 2.0-liter turbocharged four-cylinder, standard AWD, and the same polished 8-speed automatic, so you still get the smooth, quiet, premium feel that defines the model.
• xDrive M40i: This is the performance-oriented choice, with a 3.0-liter turbocharged inline six rated at 355 hp and 369 lb-ft of torque, plus upgraded brakes and a sport suspension. If you want the strongest acceleration and a more aggressive setup, this is the one to target.

The safety content notes that forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control require option packages, so check carefully for those features on any trim you consider.

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

This looks like a moderate, selective buyer’s market, so you have room to shop, but the best listings can still move quickly.

• Deal availability: 34.2% of listings are priced as good or great deals.
• Inventory: There are 1,762 listings available.
• Price trend: Prices have softened 6.58% compared with last year.
• Clean inventory: 68.8% of listings are accident-free.

If you find a listing below $17,373, 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 $17,714 sits slightly below last year's $18,962.

That decline suggests the market has already adjusted downward, which can help you buy more affordably now but may also limit short-term upside if you plan to resell soon. If you keep the vehicle in strong condition and maintain it well, you’ll be better positioned to preserve value relative to similar examples with accident history or missing equipment.

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 pre-collision system that can shut the sunroof, windows, and pre-tension the seat belts if it detects an imminent crash. The car can also disable the battery, apply the brakes, and unlock the doors automatically after a crash. Driver assists like forward-collision alert, auto braking with pedestrian detection, and adaptive cruise control are only available with two option packages, while blind-spot monitoring and lane-departure warning come with a separate package.

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:

• 34.2% of listings are priced as good or great deals.
• At 68.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Prices have softened 6.58% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The expert review highlights that this is a complete overhaul year, so you’re getting the third-generation X3 rather than an older carryover.

The bottom line: If you want the freshest version of this X3 generation and you value the updated tech, cabin quality, and premium feel, the 2018 is the right path to focus on. If your priority is stretching your budget, a nearby year may offer a lower entry price, but the 2018’s redesign and softened pricing make it the more compelling choice for shoppers who want the newest body style without paying new-car money.
