Used 2021 BMW 4 Series for Sale nearWashington, DC

How much does the 2021 BMW 4 Series cost?

Prices have softened 5.70% compared to this time last year, making it a favorable time to shop this model year.

There are 653 listings available, which suggests you have a workable amount of inventory to compare.

Is the 2021 BMW 4 Series a good car?

Yes — the 2021 BMW 4 Series earns a 5/5 user rating and a 6.83/10 expert rating. The standout strength is Technology at 9/10.

It stands out for its styling, with a more fashion-forward, bigger, and more luxurious take on the coupe formula. It also offers real variety in body styles and drivetrains, and the test-drive notes point to great handling and impressive technology as strengths.

The trade-offs are worth weighing: the design is potentially polarizing, a manual transmission is not available, and the back seat is cramped. That makes it a better fit if you want a premium two-door that emphasizes style, handling, and tech over everyday practicality.

Only 34.0% of listings are priced as good or great deals, so the market is selective rather than broadly discounted.

Is the 2021 BMW 4 Series reliable?

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

The 2021 BMW 4 Series is described as impressively refined and user friendly, which supports the case for a well-sorted ownership experience. Its performance notes also point to a composed chassis and strong grip, while the powertrain lineup uses familiar turbocharged engines and an eight-speed automatic.

On the cost side, BMW includes four years of free roadside assistance, which is a helpful ownership perk. For used buyers, the main long-term risk is that luxury-car upkeep and option content can make a neglected example more expensive to live with.

What should I look for when buying a used 2021 BMW 4 Series?

Accident-free inventory is solid at 79.9% — always verify the vehicle history report.

You should still check the history report carefully and prioritize a pre-purchase inspection, especially on cars with higher mileage or expensive option packages. Focus on overall condition, because the 4 Series can be a pricey car to bring back to top shape if it has been neglected.

Key things to evaluate:

• Trim level: The 4 Series is offered as a coupe or convertible, and the lineup includes 430i and M440i configurations. The coupe’s standard equipment includes LED headlights and taillights, front sport seats with 10-way power adjustment and driver’s memory, paddle shifters, and a leather-wrapped sport steering wheel. The cabin is clean and uncluttered, but the interior materials in the test car were good rather than truly luxurious, so base-trim shoppers should pay close attention to finish quality and option content.
• Powertrain: The 430i uses a 2.0-liter turbocharged four-cylinder with 255 horsepower and 294 pound-feet of torque. The M440i uses a 3.0-liter turbocharged inline-six with 382 horsepower and 369 pound-feet of torque, plus a 48-volt starter/generator for better fuel efficiency. An eight-speed automatic is the only transmission.
• Safety package: Standard driver-assist features include lane-departure warning, forward-collision warning, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, automatic high beams, and speed-limit information. Adaptive cruise control requires the Driving Assistance Professional Package, which also adds steering assist and stop-and-go capability.
• Infotainment: The standard setup includes an 8.8-inch touchscreen and an instrument cluster with analog gauges and a 5.1-inch display screen. The optional Live Cockpit Professional setup upgrades to a 10.25-inch central touchscreen and a 12.3-inch all-digital instrument cluster. Wireless Apple CarPlay and Android Auto are standard, and BMW’s iDrive rotary controller remains a major usability advantage.
• Fuel efficiency: The rear-wheel-drive 430i is rated at 29 mpg combined, 26 mpg city, and 34 mpg highway. The xDrive version is rated at 27 mpg combined, 24 mpg city, and 33 mpg highway.

Which 2021 BMW 4 Series trim should I buy?

The 2021 BMW 4 Series is offered in 2 trim levels: 430i and M440i.

Here's the short version:

• 430i: This is the value play if you want the core 4 Series experience without stepping up to the six-cylinder model. You still get the stylish coupe or convertible body, strong standard tech, and the same basic luxury-car presentation, while the 2.0-liter turbo four-cylinder delivers plenty of everyday performance. If you care most about price and still want the design and technology that define this model year, this is the trim to start with.
• M440i: Choose this if you want the stronger straight-line performance and the more upscale powertrain. Its 3.0-liter turbo inline-six and 48-volt starter/generator give it the most compelling performance story in the lineup, and many of the sport-oriented hardware items are standard here. It makes the most sense if you want the quickest and most richly equipped version.

Adaptive cruise control is not standard; you need the Driving Assistance Professional Package to get it.

Is now a good time to buy a used 2021 BMW 4 Series?

This looks like a moderate buyer’s market, so you can shop selectively without expecting deep bargains everywhere.

• Deal availability: 34.0% of listings are priced as good or great deals.
• Inventory: There are 653 listings available.
• Price trend: Prices have softened 5.70% compared with last year.
• Clean inventory: 79.9% of listings are accident-free.

If you find a listing below $32,023, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 BMW 4 Series's resale value?

The current average of $32,765 sits slightly below last year's $34,745.

That softer pricing suggests the model has already moved through a meaningful part of its depreciation curve. For a future seller, that can be a mixed signal: you may not see rapid appreciation, but you also may be buying after some of the steepest value loss has already happened.

Because the market is still showing steady demand and the model carries a strong satisfaction rating, well-kept examples should remain easier to move than neglected ones. Condition, mileage, and option content will matter a lot when it comes time to sell.

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 2021 BMW 4 Series safe?

It earns six-star ratings from neither NHTSA nor IIHS because crash-test ratings for this model year are not available yet.

It earns a 6/10 safety score from our experts.

Standard driver-assistance features include lane-departure warning, forward-collision warning, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, automatic high beams, and speed-limit information. If you want adaptive cruise control, you need the Driving Assistance Professional Package, which also adds steering assist and stop-and-go functionality.

Should I buy a 2021 BMW 4 Series or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 34.0% of listings are priced as good or great deals.
• Accident-free inventory is solid at 79.9% — always verify the vehicle history report.
• Price trend: Prices have softened 5.70% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 stands out for its styling, handling, and impressive technology.

Consider the 2022 if:

• At $35,312, the 2022 costs more than the current year's $32,765 average.
• It adds a five-door hatchback body style with easier rear-seat access and more cargo utility.

The bottom line: If you want the lower price and the classic coupe-or-convertible 4 Series formula, the 2021 is the better buy. If you need easier rear-seat access and more everyday practicality, the 2022 is the smarter alternative, even at a higher price.
