Used 2020 BMW 8 Series for Sale near Michigan

How much does the 2020 BMW 8 Series cost?

Prices have softened 6.59% compared to this time last year, making it a favorable time to shop this model year.

There are 207 listings available, which gives you a modest amount of inventory to compare.

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’s grand touring focus also fits buyers who want a high-end road-trip vehicle that still feels engaging to drive.

The main trade-off is that the back seat is cramped, and the interior can feel a bit basic for the class. That makes it a stronger fit if you care more about driving character and upscale front-seat comfort than rear-passenger space.

With 29.5% of listings marked as good or great deals, you have 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. Reviewers also describe it as reliable, dependable, and trouble-free enough to inspire confidence for long-term ownership.

The expert evaluation also points to a car that feels composed and well sorted in daily use, with a powertrain that manages power well and a cabin built for comfortable distance driving. BMW 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 has been neglected or heavily optioned.

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

At 72.9% 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 in any collision or has a long option list. Focus on condition, maintenance records, and whether the car’s technology and comfort features still work as intended.

Key things to evaluate:

• Trim level: The 840i comes extremely 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 lower front-end design, and dark 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 a manual mode.
• Safety package: The 840i Gran Coupe comes standard with forward-collision warning, automatic emergency braking, pedestrian detection, and adaptive LED headlights. 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 standard after the first year of complimentary access, and wireless device charging comes standard as well.
• Fuel efficiency: The 840i Gran Coupe returns 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 at the lowest entry price. You still get the strong standard equipment list, the inline-six powertrain, and the grand touring character that defines the car.
• 840i xDrive: Choose this if you want the same overall formula with all-wheel drive. It makes sense if traction and all-weather confidence matter more to you than keeping the price down.
• M850i: This is the performance step-up, with the V8 and the highest output in the lineup. It suits you if you want the most power 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.

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 carefully and still find worthwhile listings.

• Deal availability: 29.5% of listings are priced as good or great deals.
• Inventory: There are 207 listings available.
• Price trend: Prices have softened 6.59% compared with last year.
• Clean inventory: 72.9% 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 $40,883 sits slightly below last year's $43,769.

That decline suggests the market has already adjusted downward, which can help you buy at a more favorable point in the cycle. If you plan to resell later, the current pricing trend means your future value will depend heavily on condition, mileage, and how well the car has been maintained.

Because the model still has strong owner satisfaction and a desirable luxury-sport image, well-kept examples should remain easier to sell than neglected ones. Clean history and strong equipment will matter a lot when it comes time to trade or list it.

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?

The BMW 840i Gran Coupe comes standard with advanced driver assistance features, including forward-collision warning, automatic emergency braking, pedestrian detection, and adaptive LED headlights.

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

BMW also offers adaptive cruise control, lane-departure warning, blind-spot monitoring, rear cross-traffic alert, and traffic jam assistant. That gives you a useful mix of standard and available safety tech, though some of the more advanced features are not included on every trim.

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:

• 29.5% of listings are priced as good or great deals.
• At 72.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 6.59% compared with last year.
• Owners rate it 4.2/5 — a solid satisfaction signal.
• It delivers a grand touring focus with strong performance and long-distance comfort.

Consider the 2021 if:

• At $46,660, the 2021 costs more than the current year's $40,883 average.
• It adds a more upscale, higher-stature feel with greater prestige.

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