Used 2021 BMW 8 Series for SaleNationwide

How much does the 2021 BMW 8 Series cost?

Prices have softened 9.45% compared to this time last year, making it a favorable time to shop this model year.

There are 239 listings available, which suggests you have some room to compare options before you buy.

If you find a listing below $46,468.85, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2021 BMW 8 Series a good car?

Generally — the 2021 BMW 8 Series earns a 4.25/5 user rating and a 7.83/10 expert rating.

The model scores 9/10 across Look and feel and Performance.

It comes across as a statement car: the 8 Series is positioned as a high-end coupe and convertible lineup with dramatic styling, strong performance, and premium technology. The cabin quality is a major part of the appeal, and the Gran Coupe body style adds usable room for a family of four.

The trade-offs are clear. The back seat is cramped, visibility is poor, and you do not get a manual transmission. Those compromises matter most if you want everyday practicality rather than a luxury grand tourer.

With 29.7% of listings marked as good or great deals, you have a decent chance of finding a competitive price if you shop carefully.

Is the 2021 BMW 8 Series reliable?

Owners rate it 4.25/5, a solid signal of long-term satisfaction.

The 8 Series is built around premium hardware and a polished driving experience, and the expert evaluation describes it as easy to love despite its high-end positioning. Its performance and cabin refinement suggest a car that should feel special over time if it has been maintained properly.

The performance evaluation also notes that the car drives easily and effortlessly when you are not pushing it, which is a good sign for everyday usability. On the cost side, BMW’s positioning of the model in a higher price bracket means ownership can still be expensive, even if the car itself feels well engineered.

For used buyers, the main long-term risk is paying luxury-car money for a vehicle that may have been driven hard or maintained inconsistently.

What should I look for when buying a used 2021 BMW 8 Series?

Accident-free inventory is solid at 75.3% — always verify the vehicle history report.

You should still run a history report on every candidate and prioritize a pre-purchase inspection, especially on a car with this kind of performance and technology content. Focus on body condition, wheel and tire wear, and signs that the car has been used carefully rather than aggressively. Because the 8 Series sits in a premium segment, small cosmetic or mechanical issues can become expensive quickly.

Key things to evaluate:

• Trim level: The lineup includes coupe, convertible, and four-door Gran Coupe body styles, and the Gran Coupe stands out for being remarkably roomy inside. Base-level equipment already includes premium luxury and technology, but higher-spec test vehicles added items like advanced driver-assistance packages, upgraded audio, and luxury interior touches.
• Powertrain: The M850i specification uses a twin-turbocharged 4.4-liter V8 with xDrive all-wheel drive, producing 523 horsepower and 553 pound-feet of torque. It is quick, smooth, and easy to drive, but the evaluation also notes that fuel economy fell short of the official combined estimate in testing.
• Safety package: Standard equipment includes forward-collision warning with pedestrian detection, low-speed automatic emergency braking, lane-departure warning, and Active Guard. Available upgrades add blind-spot monitoring, surround-view cameras, parking sensors, and the Driving Assistance Professional Package with adaptive cruise control, lane-keeping, lane-centering, lane-changing assistance, evasive-steering assistance, and cross-traffic warning.
• Infotainment: The car uses iDrive 7.0 with a 10.25-inch touchscreen, plus voice, gesture, and physical controls. It also includes smartphone connectivity, Apple CarPlay, Android Auto, satellite radio, connected services, and a WiFi hotspot.
• Fuel efficiency: The M850i Gran Coupe averaged 17.8 mpg in testing, and the official combined figure mentioned in the evaluation is 20 mpg.

Which 2021 BMW 8 Series trim should I buy?

The 2021 BMW 8 Series is offered in 1 trim level: M850i xDrive.

Here's the short version:

The M850i xDrive is the clear choice if you want the full 8 Series experience, because it combines the V8 powertrain, xDrive traction, and the strongest luxury-and-performance mix described in the evaluation. It is the version that best matches the car’s mission as a high-end statement vehicle, and it delivers the standout acceleration and composure that define this model year.

Close attention should go to the available safety package, because the standard driver-assistance setup is good, but the Driving Assistance Professional Package adds the most advanced features.

Is now a good time to buy a used 2021 BMW 8 Series?

This is a moderate market for selective buyers, so you can shop with some leverage if you are patient.

• Deal availability: 29.7% of listings are priced as good or great deals.

• Price trend: Prices have softened 9.45% compared with last year.

If you find a listing below $46,468.85, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 BMW 8 Series's resale value?

The current average of $47,556 sits slightly below last year's $52,522.

That decline suggests the market has already adjusted downward, which can help you buy more confidently now. For a future seller, it also means the car may face some pricing pressure if broader demand stays soft in this segment. Still, the 8 Series remains a premium, image-driven model, so well-kept examples should continue to attract attention from shoppers who want something distinctive.

Vehicles with solid owner satisfaction ratings, like this model year's 4.25/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 BMW 8 Series safe?

It earns an 8/10 safety score from our experts.

Standard safety features for the BMW 8 Series include forward-collision warning with pedestrian detection, low-speed automatic emergency braking, lane-departure warning, and Active Guard. That system adds driver monitoring, collision-preparation functions such as automatic seatbelt tightening and automatic window closure, and post-collision braking.

Available upgrades include active blind-spot monitoring, semi-autonomous parking assistance, a surround-view camera system, and parking sensors. The Driving Assistance Professional Package adds adaptive cruise control with lane-keeping, lane-centering, and lane-changing assistance, plus evasive-steering assistance and front and rear cross-traffic warning systems.

The evaluation also notes a caveat with the speed limit-assisted version of adaptive cruise control, which can be distracting to switch off. The Steering Assistant is helpful, but it is not a hands-free system.

Should I buy a 2021 BMW 8 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:

• 29.7% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.3% — always verify the vehicle history report.
• Price trend: Prices have softened 9.45% compared with last year.
• Owners rate it 4.25/5 — a solid satisfaction signal.
• The 2021 model emphasizes dramatic styling, strong performance, and premium technology.

Consider the 2020 if:

• At $40,850, the 2020 costs less than the current year's $47,556 average.
• It is presented as a grand touring machine that blends dynamic performance with long-distance comfort.

The bottom line: If you want the stronger all-around shopping case, the 2021 is the better pick because pricing has eased and the car delivers the full luxury-performance experience. If your priority is spending less up front, the 2020 is the smarter value play, especially if you want the same grand touring character at a lower entry price.
