Used 2021 BMW 4 Series for Sale nearAustin, TX

How much does the 2021 BMW 4 Series cost?

Prices have softened 5.71% 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 solid 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 6.8/10 expert rating. The standout strength is Technology at 9/10.

The 4 Series is aimed at you if you want a stylish two-door BMW with a premium feel, and it backs that up with great handling and impressive technology. It also leans more heavily on tech to deliver performance, which helps define its personality.

The trade-offs are clear: the design may be polarizing, a manual transmission is not available, and the back seat is cramped. If you value style, tech, and a coupe-or-convertible format more than practicality, it fits that brief well.

33.7% of listings are priced as good or great deals, so there are still some attractive opportunities in the market.

Is the 2021 BMW 4 Series reliable?

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

The 4 Series is described as refined and user friendly, and its standard warranty covers four years or 50,000 miles with four years of free roadside assistance. It also uses a straightforward turbocharged engine lineup and an eight-speed automatic, which keeps the mechanical picture relatively simple for a luxury coupe.

BMW’s standard maintenance coverage is a plus for early ownership, and the car’s tech-heavy design helps it feel modern rather than dated. For used buyers, the main long-term risk is that luxury-car upkeep can become expensive once warranty coverage ends.

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

At 74.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report before you get serious about any listing, then prioritize a pre-purchase inspection if the car has been in a collision or shows signs of uneven wear. Focus on panel alignment, tire wear, interior condition, and whether the technology and driver-assistance features work as expected.

Key things to evaluate:

• Trim level: The lineup includes coupe and convertible body styles, with standard LED headlights and taillights, front sport seats with 10-way power adjustment and driver’s memory, and a clean, uncluttered interior. The optional black leather upholstery and Live Cockpit Professional setup add more upscale appeal, while the base setup is more modest.
• 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 horsepower and 369 pound-feet of torque. An eight-speed automatic is the only transmission.
• Safety package: 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. Adaptive cruise control requires the Driving Assistance Professional Package.
• Infotainment: The standard system uses an 8.8-inch touchscreen, while the optional Live Cockpit Professional setup upgrades to a 10.25-inch central touchscreen and a 12.3-inch digital instrument cluster. Wireless Apple CarPlay and Android Auto are standard, and BMW Intelligent Personal Assistant voice control is included.
• Fuel efficiency: The rear-wheel-drive 430i is rated at 26 mpg city and 34 mpg highway, while the xDrive version is rated at 24 mpg city and 33 mpg highway. BMW also averaged 26.6 mpg in its test car.

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 six-cylinder upgrade. You still get the stylish coupe or convertible body style, strong tech, and the standard feature set that makes the car feel premium.
• M440i: This is the pick if you want the stronger engine and the more performance-focused setup. It adds the six-cylinder powertrain and brings a more serious performance character, but it costs more and makes the 4 Series a less budget-friendly buy.

The safety package is strong across the lineup, but adaptive cruise control still requires the Driving Assistance Professional Package.

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

This is a moderate market for selective buyers, with enough inventory and pricing softness to make shopping worthwhile.

• Deal availability: 33.7% of listings are priced as good or great deals.
• Inventory: There are 653 listings available.
• Price trend: Prices have softened 5.71% compared with last year.
• Clean inventory: 74.6% of listings are accident-free.

If you find a listing below $31,906, 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 $32,050 sits slightly below last year's $33,989.

That softer pricing suggests the market has cooled a bit, which can help you buy more confidently now. For a future seller, it also means resale value may depend more on condition, mileage, and equipment than on broad market momentum.

Well-kept examples with desirable tech and clean history should hold up better than neglected ones. 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. Adaptive cruise control is not standard and requires 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.

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:

• 33.7% of listings are priced as good or great deals.
• At 74.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 5.71% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It brings a redesigned, more luxurious, tech-forward coupe identity with strong handling.

Consider the 2022 if:

• At $35,250, the 2022 costs more than the current year's $32,050 average.
• It returns as a Gran Coupe with easier rear-seat access.

The bottom line: If you want the lower price and the classic coupe-or-convertible 4 Series formula, the 2021 is the better value. If you want a more practical hatchback-style body and can spend more, the 2022 is the better fit.
