Used 2021 BMW 4 Series for Sale near Florida

How much does the 2021 BMW 4 Series cost?

Prices have softened 5.50% compared to this time last year, making it a favorable time to shop this model year.

There are 649 listings available, which gives you a decent amount of inventory to compare.

If you find a listing below $32,022.58, 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 5/5 user rating suggests strong owner satisfaction, and the expert rating is 6.83/10. The standout strength is Technology at 9/10.

The 2021 4 Series is aimed at you if you want a premium two-door that feels modern and distinctive, with coupe and convertible body styles and a stronger emphasis on technology. It also brings great handling and a more luxurious feel than before, but the design is polarizing and the back seat is cramped.

The main trade-offs are a manual transmission not being available and the rear seat being tight for passengers.

With 35.4% of listings marked as good or great deals, you have 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 4 Series is described as impressively refined and user friendly, and BMW backs it with a four-year or 50,000-mile warranty plus four years of roadside assistance. Its powertrains are straightforward, with an eight-speed automatic and no manual transmission, which can simplify ownership.

BMW also notes that the 48-volt starter/generator on the M440i is there for better fuel efficiency. For used buyers, the main long-term risk is that luxury-car upkeep can be costly if the car was optioned heavily or not maintained carefully.

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

Accident-free inventory is solid at 77.5% — always verify the vehicle history report.

You should still check the history report carefully and prioritize a pre-purchase inspection, especially if the car has higher mileage or expensive options. Focus on overall condition, because luxury features and performance packages can make repairs more expensive if anything has been neglected.

Key things to evaluate:

• Trim level: The 430i gives you the core 4 Series experience with standard 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 M440i adds more performance-oriented hardware, and it suits you best if you want the stronger engine and a more aggressive setup.
• 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. The M440i also uses a 48-volt starter/generator for better fuel efficiency.
• 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: The standard setup includes an 8.8-inch touchscreen, while the available Live Cockpit Professional system upgrades you 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’s voice assistant responds to “Hey BMW.”
• Fuel efficiency: The RWD 430i is rated at 29 mpg combined, while the xDrive version is rated at 27 mpg combined. BMW says the M440i’s 48-volt starter/generator helps improve fuel efficiency.

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 pick if you want the core 4 Series formula without paying for the stronger six-cylinder. You still get the standard tech, the sporty chassis tuning, and the features that make the car feel upscale, so it makes the most sense for you if you care more about style and equipment than outright speed.
• M440i: Choose this if you want the more powerful engine and a more performance-focused setup. It adds the stronger inline-six and the hardware that makes the car feel more serious, but it is the pricier choice.

Adaptive cruise control is not standard and 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, so it pays to compare listings carefully and move quickly on the right car.

• Deal availability: 35.4% of listings are priced as good or great deals.
• Inventory: There are 649 listings available.
• Price trend: Prices have softened 5.50% compared with last year.
• Clean inventory: 77.5% of listings are accident-free.

If you find a listing below $32,022.58, 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 $32,769 sits slightly below last year's $34,677.

That softer pricing suggests the market has already adjusted downward, which can help you buy at a more favorable point. For a future seller, it also means you should expect depreciation pressure to remain part of the ownership picture.

The good news is that the model still has clear appeal thanks to its technology, premium image, and strong owner satisfaction. Those traits can help support demand when it is time for you 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 a 6/10 safety score from our experts.

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 is available only with the Driving Assistance Professional Package, which also adds steering assist and stop-and-go capability.

The main caveat is that published crash-test ratings from NHTSA and IIHS are not available yet, so you do not get a formal test result to lean on when shopping used.

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:

• 35.4% of listings are priced as good or great deals.
• Accident-free inventory is solid at 77.5% — always verify the vehicle history report.
• Price trend: Prices have softened 5.50% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It emphasizes a redesigned look, more luxury, and stronger technology.

Consider the 2022 if:

• At $35,878, the 2022 costs more than the current year's $32,769 average.
• It adds a five-door Gran Coupe body style with easier rear-seat access.

The bottom line: If you want the lower price and the coupe-or-convertible identity, the 2021 is the better starting point. If you want easier rear-seat access and can spend more, the 2022 is the more practical alternative.
