How much does the 2018 BMW X3 cost?

Prices have softened 5.66% compared to this time last year, making it a favorable time to shop this model year.

There are 1,815 listings available, which gives you a solid pool to compare prices and equipment.

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 X3 stands out because it was completely overhauled, so you’re looking at a third-generation redesign rather than a light refresh. It’s a compact BMW crossover with a distinctive feel in a crowded segment, and its appeal is strongest if you want a practical SUV with premium-brand cachet and a fresh design.

The market also shows 34.6% of listings priced as good or great deals, which suggests there are 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 X3’s redesign and BMW’s emphasis on a refined driving experience point to a vehicle that feels well sorted in daily use. The expert review also highlights a smooth 8-speed automatic, strong turbo-four performance, and a quiet, cushy ride, all of which support the impression of a well-engineered luxury crossover.

BMW 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 that luxury options and repairs can become expensive once the included maintenance period is behind you.

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

At 70.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report and prioritize a pre-purchase inspection, especially if the listing has any accident history or a long option list. Focus on overall condition, maintenance records, and whether the equipment on the car matches what you expect for the trim and packages.

Key things to evaluate:

• Trim level: The cabin uses standard SensaTec vinyl, while leather is available, and the panoramic moonroof and large side glass help the X3 feel airy and more like a larger SUV. Higher equipment levels add more upscale convenience and tech, so base-trim cars may feel noticeably simpler.
• Powertrain: The standard 2.0-liter turbocharged inline-four is rated at 248 horsepower and 258 pound-feet of torque, while 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 8-speed automatic is described as exceptionally smooth.
• Safety package: Forward-collision alert, automatic emergency braking with pedestrian detection, and adaptive cruise control are bundled into option packages rather than being standard. Blind-spot monitoring and lane-departure warning come with the Driving Assistance package, while the more advanced package adds the other driver-assistance features.
• 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 with fast voice recognition and navigation.
• Fuel efficiency: No fuel-economy figure is stated in the available data.

Which 2018 BMW X3 trim should I buy?

The 2018 BMW X3 is offered in 2 trim levels: xDrive30i and xDrive M40i.

Here's the short version:

• xDrive30i: This is the best-value choice if you want the core X3 experience without stepping up to the pricier performance model. It gives you the standard turbocharged four-cylinder, standard AWD, and the same smooth 8-speed automatic, along with the X3’s strong tech and roomy-feeling cabin.
• xDrive M40i: Choose this if you want the stronger 3.0-liter turbo inline-six, upgraded brakes, sport suspension, and a more aggressive look. It’s the right pick if performance matters more to you than value.

BMW’s safety tech is split across option packages, so check carefully for the Driving Assistance and Driving Assistance Plus equipment before you buy.

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 but still enough variation in condition and equipment to reward patience.

• Deal availability: 34.6% of listings are priced as good or great deals.
• Inventory: There are 1,815 listings available.
• Price trend: Prices have softened 5.66% compared with last year.
• Clean inventory: 70.5% 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 $17,937 sits slightly below last year's $19,013.

That decline suggests the market has softened, which can help you as a buyer today but may temper resale expectations if you plan to sell in the near future. If you buy at the right price and keep the vehicle in strong condition, you’ll be better positioned to preserve value when it’s time to move on.

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 option packages, including forward-collision alert, automatic emergency braking with pedestrian detection, adaptive cruise control, blind-spot monitoring, and lane-departure warning. The X3 also includes uncommon safety touches 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.

A key caveat is that the more advanced driver-assistance features are not standard, so you’ll want to verify exactly which package a used example has before you buy.

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:

• 34.6% of listings are priced as good or great deals.
• At 70.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 5.66% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2018 model year is notable because it introduced the third-generation X3 as a complete overhaul, giving you the clean-break redesign rather than the older generation.

The bottom line: If you want the newer-generation X3 with the strongest mix of fresh design, premium feel, and modern tech, the 2018 is the right target. 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 all-around choice for many used buyers.
