Used 2021 BMW 4 Series for Sale nearDallas, TX

How much does the 2021 BMW 4 Series cost?

Prices have softened 4.54% compared to this time last year, making it a favorable time to shop this model year.

There are 638 listings available, which suggests you have a workable amount of inventory to compare. If you find a listing below $32,035.22, that's toward the low end of the year-round range and worth acting on quickly.

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 fits you best if you want a premium two-door that feels modern and distinctive, with coupe and convertible body styles and a stronger emphasis on tech than on old-school simplicity. The expert take also points to great handling and impressive technology, while noting that the design is polarizing and the back seat is cramped.

The main trade-offs are the lack of a manual transmission and a driving experience that can feel less engaging than the hardware suggests. Even so, 29.0% of listings are priced as good or great deals, which gives you some room to shop selectively.

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, and its powertrains are presented as quick and efficient for the class. The 430i uses a turbocharged four-cylinder, while the M440i adds a turbocharged inline-six with a 48-volt starter/generator for better fuel efficiency.

BMW also backs it with a four-year or 50,000-mile warranty and four years of roadside assistance. For used buyers, the main long-term ownership risk is that luxury-car upkeep and repair costs can rise quickly once warranty coverage ends.

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

Accident-free inventory is solid at 78.2% — always verify the vehicle history report.

You should still run a history report on any car you’re considering, because a clean listing percentage does not replace a documented record. Prioritize a pre-purchase inspection, especially if the car has larger wheels, performance packages, or higher-mileage use. Focus on condition details that matter in a luxury coupe: interior wear, tire condition, and whether the car has the equipment you want.

Key things to evaluate:

• Trim level: The cabin is clean and uncluttered, with standard front sport seats, 10-way power adjustment, driver’s memory, paddle shifters, and a leather-wrapped sport steering wheel. The base setup is well equipped, but the optional Live Cockpit Professional and leather upholstery help the car feel more upscale.
• Powertrain: The 430i uses a 2.0-liter turbocharged four-cylinder with 255 horsepower and 294 pound-feet of torque, while the M440i uses a 3.0-liter turbocharged inline-six with 382 hp and 369 lb-ft of torque. The 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.
• Infotainment: Standard iDrive 7 includes an 8.8-inch touchscreen and a 5.1-inch display in the gauge cluster. Wireless Apple CarPlay and Android Auto are standard, and the optional Live Cockpit Professional setup adds a 10.25-inch central touchscreen and a 12.3-inch digital instrument cluster.
• 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 better-value choice if you want the core 4 Series experience without paying for the stronger six-cylinder. You still get the standard tech, the coupe or convertible body style, and the handling balance that defines the car.
• M440i: This is the one to choose if you want the stronger engine and the more performance-focused setup. It adds the six-cylinder powertrain and is the right pick if you care more about speed and response than keeping the price down.

The Driving Assistance Professional Package is the key safety-package upgrade if you want adaptive cruise control and lane-centering support.

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

The market looks selective rather than overheated, so you can shop carefully and still find opportunities.

• Deal availability: 29.0% of listings are priced as good or great deals.
• Inventory: There are 638 listings available.
• Price trend: Prices have softened 4.54% compared with last year.
• Clean inventory: 78.2% of listings are accident-free.

If you find a listing below $32,035.22, 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 $32,796 sits slightly below last year's $34,356.

That price movement suggests the model has already absorbed some depreciation, which can help if you buy used and plan to sell later. A softer market today can also mean less downside risk than when prices are still climbing. If you buy at the right number and keep the car in strong condition, you may be better positioned when it is time to trade or 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 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 capability.

Crash-test ratings from NHTSA and IIHS are not available yet for this model year. For used buyers, that means you should lean more heavily on the car’s equipment list and condition history when evaluating safety.

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:

• 29.0% of listings are priced as good or great deals.
• Accident-free inventory is solid at 78.2% — always verify the vehicle history report.
• Price trend: Prices have softened 4.54% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 model emphasizes a redesigned look, more technology, and coupe/convertible flexibility.

Consider the 2022 if:

• At $36,216, the 2022 costs more than the current year's $32,796 average.
• It adds a five-door Gran Coupe body style with easier rear-seat access.

The bottom line: If you want the lower entry price and the classic coupe-or-convertible setup, the 2021 is the better starting point. If you value easier rear-seat access and extra practicality, the 2022 is worth the higher asking price.
