Used 2020 BMW 8 Series for Sale nearChicago, IL

How much does the 2020 BMW 8 Series cost?

Prices have softened 7.90% compared to this time last year, making it a favorable time to shop this model year.

There are 205 listings available, which suggests you have some room to compare options. If you find a listing below $40,542.63, 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 also fits the grand touring use case well, since it is meant to deliver strong driving dynamics while still covering long distances in comfort.

The main trade-offs are a cramped rear seat and an interior that some owners feel can seem basic for a luxury car. Even so, the combination of driving enjoyment and upscale equipment makes it appealing if you want a high-end road-trip car rather than a chauffeur-focused cruiser.

With 33.7% of listings marked as good or great deals, the market gives you a decent chance to find value if you shop carefully.

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 daily use, with strong praise for the performance, tech, and overall ownership experience. That kind of response suggests you can count on it to deliver the premium driving character buyers expect.

The expert evaluation also reinforces that impression by describing the 8 Series as a refined grand touring machine that handles long distances with ease. The standard maintenance and ownership experience should still be weighed carefully on the used market, since luxury-car upkeep can become expensive over time.

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

At 69.8% 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 had any bodywork or electronic repairs. Focus on condition details that matter in a luxury grand tourer: interior wear, seat function, and evidence that the technology and driver-assistance systems work properly.

Key things to evaluate:

• Trim level: The 840i comes very 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 steps up to 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 a manual mode.
• Safety package: Standard equipment includes forward-collision warning, automatic emergency braking, pedestrian detection, and adaptive LED headlights. Available features include adaptive cruise control, lane-departure warning, blind-spot monitoring, rear cross-traffic alert, and traffic jam assistant.
• Infotainment: BMW’s iDrive system includes a touchscreen plus the legacy button-and-joystick controller. Wireless Apple CarPlay and wireless device charging are standard, and the system also includes gesture control.
• Fuel efficiency: The 840i Coupe returns 23 mpg city, 30 highway, 25 combined. The 840i Convertible and Gran Coupe return 22 mpg city, 29 highway, 24 combined. The M850i returns 18 mpg city, 25 highway, 20 combined, with the M850i Gran Coupe at 17 mpg city.

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. It delivers the standard inline-six powertrain, strong equipment, 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 traction and all-weather confidence matter more to you than keeping the price lower.
• M850i: Pick this if you want the most power and the most aggressive performance character in the lineup. It adds the V8 and is the right choice if you care most about straight-line speed and top-end capability.

The standard safety equipment is strong, and additional driver-assistance features are available on higher-spec or optioned versions.

Is now a good time to buy a used 2020 BMW 8 Series?

If you find a listing below $40,542.63, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $40,646 sits slightly below last year's $44,134.

That price movement suggests the model has already absorbed some depreciation, which can help future resale stability if you buy at the right price. If you keep the car in strong condition and avoid accident history, you may be better positioned when it is time to sell. The current market also shows enough demand to support a used luxury coupe or grand touring car with the right equipment and 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 an 8/10 safety score from our experts.

The 840i Gran Coupe comes standard with forward-collision warning, automatic emergency braking, pedestrian detection, and adaptive LED headlights. Standard safety equipment also includes traction control, active front head restraints, child seat anchors, and a full array of front- and side-impact airbags.

Available driver-assistance features include adaptive cruise control, lane-departure warning, blind-spot monitoring, rear cross-traffic alert, and the traffic jam assistant. One caveat is that the adaptive cruise control can brake abruptly when it closes on traffic, which may surprise drivers behind you.

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:

• 33.7% of listings are priced as good or great deals.
• At 69.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.90% compared with last year.
• Owners rate it 4.2/5 — a solid satisfaction signal.
• It delivers a grand touring focus with strong performance and impressive technology.

Consider the 2021 if:

• At $47,335, the 2021 costs more than the current year's $40,646 average.
• It adds a more status-forward luxury presentation.

The bottom line: If you want the better value, the 2020 is the smarter buy because it combines strong performance, good tech, and a lower average price. If you care more about newer-model prestige and are willing to pay more, the 2021 is the alternative to consider.
