How much does the 2020 BMW Z4 cost?

Prices have softened 1.69% compared to this time last year, making it a favorable time to shop this model year.

There are 90 listings available, which gives you a modest amount of inventory to compare across trims and option packages.

If you find a listing below $35,292.65, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 BMW Z4 a good car?

Yes — the 2020 BMW Z4 earns a 4.71/5 user rating, and our experts rate it 7.5/10 overall. The standout strength is Performance at 9/10.

Owners consistently praise the performance, handling, comfortable seats, smooth transmission, and powerful engine. The overview also frames it as a fun-to-drive roadster with great handling, which fits the way shoppers tend to use this car: as a compact, open-top driver’s car rather than a pure commuter.

The main trade-off is outdated technology, and some owners also mention road noise from the soft top. Even so, the market still shows 40.0% good or great deals, which suggests you can shop with some leverage if you’re willing to compare examples carefully.

Is the 2020 BMW Z4 reliable?

Owners rate it 4.71/5, a strong signal of long-term satisfaction.

The owner feedback points to a car that feels dependable in the ways that matter to enthusiasts: strong performance, a smooth transmission, and a powertrain that owners clearly enjoy living with over time. The expert drive notes also reinforce that the Z4’s power delivery is confident and well sorted, which supports the impression of a car you can count on for spirited use.

The cost-effectiveness discussion also frames the Z4 as a compelling value relative to rivals, especially when you compare its performance and luxury content against pricier alternatives. For used buyers, the main long-term ownership risk is that a roadster with more complex features and a premium badge can become expensive if prior maintenance or option-package equipment was neglected.

What should I look for when buying a used 2020 BMW Z4?

Accident-free inventory is solid at 75.6% — always verify the vehicle history report.

You should start with a history report and then prioritize a close inspection of the soft top, cabin electronics, and any option-package equipment on the car you’re considering. Because the Z4’s appeal depends heavily on how well it drives and how well its features work, condition matters more than mileage alone. Pay extra attention to signs of wear that could affect comfort, visibility, or day-to-day usability.

Key things to evaluate:

• Trim level: The base sDrive30i gives you a 10.24-inch touchscreen, navigation, HD Radio, 14-way power and memory seats, automatic LED headlights, rain-sensing wipers, auto-dimming mirrors, and automatic climate control, but it does not include Android Auto. The M40i adds the inline-six engine and more standard equipment, making it the stronger choice if you want the full Z4 experience.
• Powertrain: The sDrive30i uses a 2.0-liter turbocharged 4-cylinder with 255 hp and 295 lb-ft of torque, while the M40i brings back a 3.0-liter turbocharged inline-6 with 382 hp and 368 lb-ft. The 4-cylinder is lighter and still quick, but the inline-6 is the one that delivers the car’s signature punch.
• Safety package: Standard safety equipment includes frontal collision warning with emergency braking and traffic-sign recognition. The Driving Assistance package adds blind-spot monitoring and lane-departure warning, while the Convenience package adds rear cross-traffic alert, an automatic parking system, satellite radio, adaptive cruise, and smartphone key pairing.
• Infotainment: The Z4 uses a 10.24-inch touchscreen with BMW iDrive. Apple CarPlay is offered, but Android Auto is missing. The tech setup is easy to live with in some ways, but the interface can be less intuitive than you’d want.
• Fuel efficiency: The 4-cylinder reaches 60 mph in about 5.5 seconds and is described as the lighter, more efficient-feeling choice, while the inline-6 is the performance-focused option. No mpg figure is stated here.

Which 2020 BMW Z4 trim should I buy?

The 2020 BMW Z4 is offered in 2 trim levels: sDrive30i, M40i.

Here's the short version:

• sDrive30i: This is the entry point, but it still gives you a well-equipped roadster with the 10.24-inch touchscreen, navigation, HD Radio, 14-way power and memory seats, automatic LED headlights, rain-sensing wipers, and automatic climate control. It’s the better fit if you want the Z4’s style and handling without paying for the six-cylinder upgrade.
• M40i: This is the trim to choose if you want the Z4’s defining character. It brings back the inline-6, adds much stronger acceleration, and includes more of the desirable equipment that makes the car feel special. If you care most about performance, this is the best-value trim to target.

The safety package is straightforward: the standard setup includes frontal collision warning with emergency braking and traffic-sign recognition, while the available driver-assistance package adds blind-spot monitoring and lane-departure warning.

Is now a good time to buy a used 2020 BMW Z4?

This looks like a buyer-friendly moment if you’re shopping carefully, because pricing has eased and there’s enough inventory to compare examples across trims and option combinations.

• Deal availability: 40.0% of listings are priced as good or great deals.
• Inventory: There are 90 listings available.
• Price trend: Prices have softened 1.69% compared with last year.
• Clean inventory: 75.6% of listings are accident-free.

If you find a listing below $35,292.65, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 BMW Z4's resale value?

The current average of $36,539 sits slightly below last year's $37,168.

That kind of price movement suggests the market has already absorbed some depreciation, which can help future resale stability if you buy at the right number. A softer current market can also make it easier to find a well-optioned example without paying peak pricing. For a future seller, the key will be how well the car was maintained and whether it has the desirable equipment buyers want in a roadster.

Vehicles with strong owner satisfaction ratings, like this model year's 4.71/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 BMW Z4 safe?

It earns a 6/10 safety score from our experts.

Standard safety features include frontal collision warning with emergency braking and traffic-sign recognition. The available Driving Assistance package adds blind-spot monitoring and lane-departure warning, while the Convenience package adds rear cross-traffic alert, an automatic parking system, satellite radio, adaptive cruise, and smartphone key pairing.

The safety write-up also notes relatively poor rear visibility with the top up and some visibility compromise from the wind deflector with the top down, so you should pay attention to how comfortable you feel with the car’s sightlines during a test drive.

Should I buy a 2020 BMW Z4 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:

• 40.0% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.6% — always verify the vehicle history report.
• Price trend: Prices have softened 1.69% compared with last year.
• Owners rate it 4.71/5 — a strong satisfaction signal.
• This year brings back the inline 6-cylinder engine in the M40i trim, restoring the stronger performance identity that defines the car.

The bottom line: If you want the Z4’s best mix of performance, value, and current-market availability, the 2020 is the year to focus on. If you’re especially price-sensitive, you can still shop aggressively within this year’s inventory and look for a lower-priced sDrive30i or a well-priced M40i with the right options.
