How much does the 2021 BMW 8 Series cost?

There are 238 listings available, which suggests you have a workable amount of inventory to compare.

Is the 2021 BMW 8 Series a good car?

Generally — the 4.25/5 user rating and 7.83/10 expert rating point to a car that delivers on its luxury mission. The 8 Series is positioned as a high-end luxury coupe and convertible with a strong sense of scale and prestige, and it stands out for its stylish design, powerful engine, and impressive technology.

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

That said, the trade-offs are real: the back seat is cramped, visibility is poor, and there’s no manual transmission. If you want a statement-making luxury car with serious performance and tech, it fits that brief well; if you need everyday practicality, it asks you to compromise.

32.8% of listings are priced as good or great deals, so there is still some room to shop selectively.

Is the 2021 BMW 8 Series reliable?

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

The 8 Series is described as a high-end luxury car with strong driving dynamics and a quiet, composed highway demeanor, which supports confidence in day-to-day use. Its performance hardware and well-finished cabin suggest a vehicle built to deliver a premium ownership experience, not just a flashy first impression.

The expert evaluation also notes that the car is easy to drive smoothly when you are not pushing it, which is a good sign for long-term livability. For used buyers, the main ownership risk is less about basic durability and more about the cost and complexity that can come with a high-end performance luxury car.

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

At 73.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially if the car has been driven hard or shows signs of cosmetic repair. Pay close attention to body condition, panel alignment, wheel and tire wear, and any evidence that the car’s low nose or expensive trim pieces have taken a hit.

Key things to evaluate:

• Trim level: The Gran Coupe body style is notably roomier than the coupe or convertible, and the base setup leaves you with a cramped back seat and poor visibility.
• Powertrain: The M850i specification uses a twin-turbocharged 4.4-liter V8 with xDrive all-wheel drive, 523 horsepower, and 553 pound-feet of torque.
• 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 front and rear cross-traffic warning.
• Infotainment: The car uses iDrive 7.0 with a 10.25-inch touchscreen, plus touch, voice, gesture, and physical controls; smartphone connectivity, Apple CarPlay, Android Auto, satellite radio, connected services, and a WiFi hotspot are included.
• Fuel efficiency: The M850i xDrive Gran Coupe averaged 17.8 mpg on the evaluation loop, and the official combined rating 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 Gran Coupe.

Here's the short version:

The M850i xDrive Gran Coupe: This is the trim that best captures the 8 Series formula if you want the full-strength version of the car’s luxury and performance character. It brings the twin-turbo V8, xDrive all-wheel drive, strong acceleration, and the most complete expression of the model’s upscale feel, while still offering the four-door Gran Coupe body style that makes it the most usable version of the lineup. If you want the best-value path into the 8 Series experience, this is the one to focus on.

The safety package is strongest when you add the Driving Assistance Professional Package, which layers in the most advanced driver-assistance features.

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

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you stay disciplined.

• Deal availability: 32.8% of listings are priced as good or great deals.
• Inventory: There are 238 listings available.
• Price trend: Prices have softened 10.00% compared with last year.
• Clean inventory: 73.9% of listings are accident-free.

If you find a listing below $46,468, 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 $47,087 sits slightly below last year's $52,317.

That decline suggests the market has already adjusted downward, which can help you buy more confidently now. For a future seller, it also means your resale outcome will depend heavily on condition, mileage, and how well the car is equipped and maintained.

Because the 8 Series sits in a premium niche, clean examples with desirable equipment should remain easier to market than rough or heavily used ones. 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?

The 2021 BMW 8 Series has not been crash tested by IIHS or NHTSA.

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

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

You can also get active blind-spot monitoring, a surround-view camera system, parking sensors, and semi-autonomous parking assistance. 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.

One caveat is that the speed limit-assisted adaptive cruise control can be distracting to override, and the Steering Assistant 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:

• 32.8% of listings are priced as good or great deals.
• At 73.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.00% compared with last year.
• Owners rate it 4.25/5 — a solid satisfaction signal.
• The 2021 stands out for its stylish design, powerful engine, and impressive technology.

Consider the 2020 if:

• At $40,716, the 2020 costs less than the current year's $47,087 average.
• It emphasizes the grand touring experience with performance and long-distance comfort.

The bottom line: Choose the 2021 if you want the stronger current-market value signal and the more up-to-date version of the 8 Series formula. If your priority is spending less up front, the 2020 is the better value play, especially if you find one in strong condition with the right equipment.
