If you find a listing below $40,853.90, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 BMW 8 Series a good car?

Generally — the 2020 BMW 8 Series earns a 4.2/5 user rating and an 8.67/10 expert rating. The model scores 10/10 across Performance and Technology.

Owners consistently praise the performance, sporty handling, luxurious features, tech, and interior design. The car is also framed as a grand touring machine, so you get the appeal of a high-end road-trip car that still feels engaging from behind the wheel.

The trade-offs are clear: the rear seat is cramped, and some owners feel the interior can seem basic for a luxury vehicle. Even so, the combination of driving enjoyment and long-distance comfort makes it a strong fit if you want a flagship-style coupe or grand touring sedan rather than a purely practical luxury car.

With 30.7% of listings marked as good or great deals, the market gives you some room to shop selectively.

Is the 2020 BMW 8 Series reliable?

Owners rate it 4.2/5, a solid signal of long-term satisfaction.

The owner feedback points to a car that feels dependable in the ways that matter most to used buyers: strong performance, enjoyable driving manners, and a package that owners are happy to live with over time. The emphasis on sporty handling, luxurious features, and tech also suggests a model that tends to satisfy buyers who plan to keep it for the long haul.

The expert drive notes reinforce that impression by describing the car as a composed grand touring machine that can cover long distances in comfort. BMW also includes standard equipment such as remote start, heated front seats, a heated steering wheel, and wireless charging, which helps the car feel well equipped from the start.

For used buyers, the main long-term ownership risk is that luxury-car upkeep can become expensive if the car has been neglected or heavily optioned.

What should I look for when buying a used 2020 BMW 8 Series?

At 67.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a full vehicle history report and then prioritize a pre-purchase inspection, especially if the car has been optioned heavily or shows signs of cosmetic wear. Focus on condition first: the 8 Series is a luxury grand tourer, so you want to make sure the interior, electronics, and ride quality still feel as polished as they should.

Key things to evaluate:

• Trim level: The 840i comes well equipped with 18-inch alloy wheels, run-flat tires, leather upholstery, a premium Nappa leather dash, remote start, a two-piece panoramic moonroof, 14-way power-adjustable front seats, a power rear sunshade, ambient cabin lighting, wireless device charging, heated front seats, a heated steering wheel, rain-sensing wipers, and a 16-speaker Harmon Kardon sound system. The M Sport design package adds 19-inch wheels, a more aggressive front-end design, and Shadowline trim, while the Comfort Seating Package adds ventilated front seats and heated rear seats.
• Powertrain: The 840i uses a twin-turbocharged 3.0-liter inline-six with 335 horsepower and 368 pound-feet of torque. The M850i uses a 4.4-liter twin-turbo V8 with 523 hp and 553 lb-ft of torque. Both pair with an eight-speed automatic transmission with paddle shifters and manual mode.
• Safety package: Standard equipment includes forward-collision warning, automatic emergency braking, pedestrian detection, adaptive LED headlights, traction control, active front head restraints, child seat anchors, and a full array of front- and side-impact airbags. Adaptive cruise control, lane-departure warning, blind-spot monitoring, rear cross-traffic alert, and traffic jam assistant are available.
• Infotainment: BMW’s iDrive system includes a touchscreen plus the legacy button-and-joystick controller. Wireless Apple CarPlay is included for one year, and wireless device charging comes standard.
• Fuel efficiency: The 840i Coupe returns 23 mpg city, 30 highway, and 25 combined. The 840i Convertible and Gran Coupe return 22 mpg city, 29 highway, and 24 combined. The M850i returns 18 mpg city, 25 highway, and 20 combined.

Which 2020 BMW 8 Series trim should I buy?

The 2020 BMW 8 Series is offered in 3 trim levels: 840i, 840i xDrive, M850i.

Here's the short version:

• 840i: This is the best-value choice if you want the core 8 Series experience without stepping into the highest price tier. You still get the strong standard equipment list, the twin-turbo inline-six, and the grand touring character that defines the car.
• 840i xDrive: Choose this if you want the same well-equipped setup as the 840i but prefer all-wheel drive. It makes sense if you want added traction without moving all the way up to the V8 model.
• M850i: This is the performance pick, with the twin-turbo V8 and the most power in the lineup. It suits you if you want the most dramatic acceleration and are willing to pay for it.

The standard safety package includes forward-collision warning, automatic emergency braking, pedestrian detection, and adaptive LED headlights, while additional driver-assistance features remain available.

What is the 2020 BMW 8 Series's resale value?

The current average of $40,850 sits slightly below last year's $44,155.

That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For a future seller, it also means you should expect resale value to depend heavily on condition, mileage, and how well the car has been maintained.

Because this is a luxury grand tourer, well-kept examples should continue to attract buyers who want performance and comfort in one package. Strong demand for the model’s driving character can help support resale value, especially if the car presents cleanly and has a solid history.

Vehicles with solid owner satisfaction ratings, like this model year's 4.2/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 BMW 8 Series safe?

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

The standard safety equipment includes forward-collision warning, automatic emergency braking, pedestrian detection, adaptive LED headlights, traction control, active front head restraints, child seat anchors, and a full array of front- and side-impact airbags. Adaptive cruise control, lane-departure warning, blind-spot monitoring, rear cross-traffic alert, and traffic jam assistant are available.

One caveat is that the traffic jam assistant can brake abruptly when it matches the pace of traffic, which may surprise drivers behind you. That doesn’t make it a bad feature, but it is worth understanding before you rely on it in dense traffic.

Should I buy a 2020 BMW 8 Series or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 30.7% of listings are priced as good or great deals.
• At 67.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.48% compared with last year.
• Owners rate it 4.2/5 — a solid satisfaction signal.
• It combines grand touring comfort with strong performance and impressive technology.

Consider the 2021 if:

• At $47,556, the 2021 costs more than the current year's $40,850 average.
• It adds a more status-focused luxury presentation with a six-figure positioning.

The bottom line: If you want the better value, the 2020 is the smarter starting point because prices have eased and the car still delivers the core 8 Series experience. If you care more about newer-year positioning and are comfortable paying more, the 2021 is the secondary path to consider.
