Used 2020 BMW 8 Series for Sale nearChicago, IL

How much does the 2020 BMW 8 Series cost?

Prices have softened 7.73% compared to this time last year, making it a favorable time to shop this model year.

There are 211 listings available, which gives you a modest pool to compare before you commit.

Is the 2020 BMW 8 Series a good car?

Generally — you’re looking at a 4.2/5 owner 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 8 Series also fits the use case of a high-end road-trip car, with the emphasis on driving yourself rather than being chauffeured.

The main trade-offs are a cramped back seat and an interior that some owners feel is a bit basic for the class. Even so, the market still shows 30.8% of listings as good or great deals, which suggests there are worthwhile opportunities if you shop carefully.

Is the 2020 BMW 8 Series reliable?

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

Owner feedback points to a car that feels dependable, trouble-free, and worth counting on, especially for buyers who value long-term satisfaction alongside performance and luxury. The expert evaluation also frames it as a refined grand touring machine that can handle long distances in comfort, which supports the idea of steady everyday usability.

The 8 Series also includes a complimentary first year of Apple CarPlay, which helps reduce early ownership friction. For used buyers, the main long-term risk is that luxury-car upkeep can become expensive if the car was not maintained carefully.

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

At 70.6% 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 any signs of prior bodywork or uneven wear. Focus on condition details that matter most in a luxury grand tourer: seat wear, electronics, and evidence that the car was maintained consistently.

Key things to evaluate:

• Trim level: The 840i comes 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 lower front-end design, and dark Shadowline trim.
• 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 a 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, along with wireless device charging and standard wired and wireless connectivity.
• Fuel efficiency: The 840i Gran Coupe returns an estimated 22 mpg city, 29 highway, 24 combined. The M850i returns 18 mpg city, 25 highway, 20 combined, and the M850i Gran Coupe falls to 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 with the standard twin-turbo inline-six, 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 for added traction.
• M850i: Pick this if you want the V8 and the most power in the lineup, and you’re willing to pay for the extra performance.

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

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

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

• Deal availability: 30.8% of listings are priced as good or great deals.
• Inventory: There are 211 listings available.
• Price trend: Prices have softened 7.73% compared with last year.
• Clean inventory: 70.6% of listings are accident-free.

If you find a listing below $40,530, 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 $40,716 sits slightly below last year's $44,125.

That decline 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 your resale outcome will depend heavily on condition, mileage, and how well the car was maintained.

Because this model has a strong owner satisfaction rating, demand should remain healthier than average for a luxury car with this kind of price movement. Well-kept examples are more likely to hold buyer interest over time.

Is the 2020 BMW 8 Series safe?

The 2020 BMW 8 Series earns an 8/10 safety score from our experts.

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.

The traffic jam assistant can move the car with traffic flow, and adaptive cruise control can match the pace of the vehicle ahead. The main caveat is that the system may brake abruptly when it closes in on traffic, which can 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:

• 30.8% of listings are priced as good or great deals.
• At 70.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.73% compared with last year.
• Owners rate it 4.2/5 — a solid satisfaction signal.
• The 2020 model emphasizes grand touring comfort with strong performance and impressive technology.

Consider the 2021 if:

• At $47,087, the 2021 costs more than the current year's $40,716 average.
• It adds a higher-price, more upscale presence with a stronger luxury-car statement.

The bottom line: If you want the better value, the 2020 is the smarter starting point because it combines strong performance, luxury, and a softer market price. If you’re willing to spend more for a newer and pricier alternative, the 2021 is the secondary path.
