Used 2020 BMW X3 M for Sale nearChicago, IL

How much does the 2020 BMW X3 M cost?

Prices have held steady compared to this time last year, signaling a stable and predictable market for this model year.

There are 98 listings available, which gives you a modest amount of inventory to compare. If you find a listing below $42,752.94, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 BMW X3 M a good car?

Yes — you’re looking at a 4.88/5 user-rated SUV with an 8.33/10 expert rating. The model scores 9/10 across Performance, Form and function, Technology, and Safety.

Drivers consistently praise its impressive power, sporty handling, and stylish design. The overview also points to a strong blend of serious performance and everyday usability, which is a big part of the appeal for shoppers who want an SUV that feels special without giving up practicality.

The main trade-offs are that the exhaust note is subdued and fuel economy may not satisfy everyone. In market terms, 31.6% of listings are priced as good or great deals, so there’s still some room to shop carefully.

Is the 2020 BMW X3 M reliable?

Owners rate it 4.88/5, a strong signal of long-term satisfaction. The user feedback also points to a vehicle that feels dependable and trouble-free in the ways that matter most to owners who want strong performance without constant drama.

The expert driving notes reinforce that impression with language about the X3 M feeling smooth and always ready to rage, which suggests a powertrain that delivers repeatable performance rather than feeling fragile. BMW also includes three-year/36,000-mile maintenance, including a brake flush and spark plugs, which helps reduce early ownership friction.

For used buyers, the main long-term risk is that a high-performance luxury SUV can become expensive if prior maintenance was skipped or if wear items were neglected.

What should I look for when buying a used 2020 BMW X3 M?

Accident-free inventory is solid at 80.6% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not replace a proper paper trail. Prioritize a pre-purchase inspection that focuses on tires, brakes, suspension wear, and signs of hard use, since this is a performance SUV that may have been driven aggressively. You should also pay close attention to condition details inside and out, because cosmetic wear can hint at how the vehicle was treated overall.

Key things to evaluate:

• Trim level: The X3 M stands apart from the more ordinary X3 trims with a much more aggressive look, including black quad exhaust pipes, gaping front intakes, blue brake calipers, and M-exclusive interior details such as quilted leather, carbon fiber trim, and heavily bolstered bucket seats. The base X3 trims are more restrained and less performance-focused.
• Powertrain: The X3 M uses a twin-turbo 3.0-liter inline-six with 473 hp, while the Competition version raises output to 503 hp and 442 pound-feet of torque. The setup is tuned for sharp response, strong grip, and track-ready urgency.
• Safety package: The standard safety equipment includes pedestrian detection, adaptive cruise control, parking sensors, and forward emergency braking. Blind-spot monitoring, lane-departure warning, lane keep assist, evasive steering assist, Traffic Jam Assist, and auto high beams are tied to optional packages, so check carefully for feature gaps.
• Infotainment: You get standard navigation, wireless Apple CarPlay, a sharp touchscreen, and onboard access to the owner’s manual. Android Auto is not offered, and wireless charging is optional.
• Fuel efficiency: The X3 M is rated at 15 mpg in the expert driving notes, and the broader performance discussion says the standard gas X3 M returns 14/19/16.

Which 2020 BMW X3 M trim should I buy?

The 2020 BMW X3 M is offered in 2 trim levels: X3 M and X3 M Competition.

Here's the short version:

• X3 M: This is the better-value choice if you want the core X3 M experience without stretching to the highest-output version. You still get the twin-turbo inline-six, the aggressive chassis tuning, and the performance-first character that defines the model.
• X3 M Competition: This is the one to choose if you want the most extreme version, with 503 hp and the most intense track-focused personality. It suits you best if outright performance matters more than comfort or cost.

The safety package is strong overall, but several driver-assistance features remain optional, so verify equipment carefully before you buy.

Is now a good time to buy a used 2020 BMW X3 M?

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you’re patient.

• Deal availability: 31.6% of listings are priced as good or great deals.
• Inventory: There are 98 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 80.6% of listings are accident-free.

If you find a listing below $42,752.94, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 BMW X3 M's resale value?

The current average of $45,087 sits slightly above last year's $45,027.

That kind of stability suggests the market has been fairly steady, which is helpful if you’re thinking about future resale. You’re not looking at a model year that appears to be sliding sharply in value, so a well-kept example should remain reasonably marketable. Strong condition, clean history, and documented maintenance matter a lot here because buyers in this segment tend to be selective.

Vehicles with strong owner satisfaction ratings, like this model year's 4.88/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 BMW X3 M safe?

The 2020 X3 is rated a Top Safety Pick+ by the Insurance Institute for Highway Safety (IIHS) and earns five-star ratings overall and in all three crash tests in all tested passenger configurations from NHTSA.

It earns a 9/10 safety score from our experts.

Standard safety equipment includes pedestrian detection, adaptive cruise control, parking sensors, and forward emergency braking. Blind-spot monitoring and lane-departure warning are optional on the Driving Assistance Package, while the Plus version adds lane keep assist, evasive steering assist, and Traffic Jam Assist for semi-automated control. Auto high beams are part of another package.

One important caveat is that these crash tests were not performed on X3 M or Competition models, even though the rating still applies.

Should I buy a 2020 BMW X3 M or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 31.6% of listings are priced as good or great deals.
• Accident-free inventory is solid at 80.6% — always verify the vehicle history report.
• Price trend: Prices have held steady compared with last year.
• Owners rate it 4.88/5 — a strong satisfaction signal.
• The 2020 stands out for combining serious performance with everyday usability, while also adding standard navigation and wireless Apple CarPlay.

The bottom line: If you want the strongest mix of performance, usability, and market stability, the 2020 is the right place to focus. If you’re more price-sensitive, you can still shop carefully within this year’s inventory and target the lower end of the range, but the best examples will reward you most when they’re clean, well maintained, and properly equipped.
