Used 2020 BMW Z4 for Sale nearLos Angeles, CA

How much does the 2020 BMW Z4 cost?

Prices have held steady compared to this time last year, signaling a stable and predictable market for this model year.

There are 86 listings available, which suggests a modest amount of inventory for shoppers comparing this roadster.

Is the 2020 BMW Z4 a good car?

Yes — the 2020 BMW Z4 earns 4.71/5 from owners and 7.5/10 from experts. The standout strength is Performance at 9/10.

Owners consistently praise the performance, handling, smooth transmission, and comfortable seats, and the overview points to a small convertible that feels especially appealing if you want serious punch in a compact package. The trade-offs are the outdated technology and some road noise from the soft top, so the Z4 makes the most sense if driving enjoyment matters more to you than the latest cabin tech.

With 37.2% of listings marked as good or great deals, you have a reasonable chance of finding a competitively priced example.

Is the 2020 BMW Z4 reliable?

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

The owner summary points to a car that feels dependable in daily use, with praise centered on performance, handling, smooth shifting, and comfortable seats. The expert review also reinforces that impression by describing the Z4 as a fun little engine package that can be configured to your preference, with the 4-cylinder noted as eager and the inline-6 as especially strong.

The cost-effectiveness review also frames the Z4 as a compelling value relative to rivals, which can help reduce ownership regret if you buy the right trim and avoid overpaying for options. For used buyers, the main long-term risk is less about outright durability than about choosing a well-kept example with the equipment and condition you want.

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

At 73.3% 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 close inspection of bodywork, panel alignment, and any signs of prior repair. Because this is a roadster, you should also pay attention to top operation, visibility, and cabin wear, since those areas can affect both day-to-day enjoyment and long-term value.

Key things to evaluate:

• Trim level: The base sDrive30i brings automatic LED headlights, rain-sensing wipers, auto-dimming mirrors, automatic climate control, 14-way power and memory seats, a 10.24-inch touchscreen, navigation, HD Radio, and Apple CarPlay, but Android Auto is missing. The M40i adds the inline-6, 19-inch wheels, and more of the performance-oriented hardware, making it the better fit if you want the stronger engine and a more complete grand-touring feel.
• Powertrain: The sDrive30i uses a 2.0-liter turbocharged 4-cylinder with 255 hp and 295 lb-ft of torque, while the M40i uses a 3.0-liter turbocharged inline-6 with 382 hp and 368 lb-ft. The 4-cylinder is eager and lighter, while the inline-6 is the one to choose if you want the strongest acceleration and the most satisfying performance character.
• Safety package: Standard 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, automatic parking, satellite radio, adaptive cruise, and smartphone key pairing.
• Infotainment: The Z4 uses a 10.24-inch touchscreen with BMW iDrive, and it includes navigation and HD Radio. Apple CarPlay is offered, but Android Auto is not, and the tech review notes that switching between screens is not especially intuitive.
• Fuel efficiency: The 4-cylinder is described as a fun little engine that can offer a slight handling advantage thanks to its reduced weight, but no MPG or MPGe figure is stated.

Which 2020 BMW Z4 trim should I buy?

The 2020 BMW Z4 is offered in 2 trim levels: sDrive30i and sDriveM40i.

Here's the short version:

• sDrive30i: This is the value play if you want the Z4 experience at the lower entry price. It already brings the core luxury and convenience features, plus the 255-hp turbocharged 4-cylinder, and it can be optioned with the Premium, Executive, and Track Handling packages if you want to tailor the car more toward comfort or sharper dynamics.
• sDriveM40i: This is the one to buy if you want the Z4 at its most complete and most entertaining. It adds the inline-6, more performance hardware, and more of the desirable equipment already built in, so it suits you best if you care most about acceleration and the strongest overall roadster character.

The safety package is optional on both trims, so you should verify whether the specific car you’re considering has the driver-assistance equipment you want.

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

This is a moderate market, so you can shop selectively without expecting a deep buyer’s market.

• Deal availability: 37.2% of listings are priced as good or great deals.
• Inventory: There are 86 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 73.3% of listings are accident-free.

If you find a listing below $35,311, 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 $36,569 sits slightly above last year's $36,384.

That small increase suggests the market has stayed stable rather than swinging sharply in either direction. For you as a future seller, that kind of pricing pattern can be helpful because it points to predictable demand and fewer surprises when it’s time to list the car.

The Z4’s appeal also benefits from its strong enthusiast identity, since buyers looking for a compact roadster tend to respond well to a car with clear performance credentials. If you keep mileage, condition, and option content in good shape, that should help support resale interest.

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?

The redesigned BMW Z4 has yet to be tested by the government’s National Highway Traffic Safety Administration (NHTSA) and the independent Insurance Institute for Highway Safety (IIHS).

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

Standard safety features include frontal collision warning with emergency braking and traffic-sign recognition, though this can be supported with the Driving Assistance package to add blind-spot-monitoring and lane-departure-warning systems, or with the Convenience package for rear cross-traffic alert, along with an automatic parking system, satellite radio, adaptive cruise, and smartphone key pairing.

The Z4 also has relatively poor rear visibility when the top is up, so you should pay close attention to how well the camera system works on the specific car you’re considering.

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:

• 37.2% of listings are priced as good or great deals.
• At 73.3% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have held steady compared with last year.
• Owners rate it 4.71/5 — a strong satisfaction signal.
• The inline 6-cylinder returns in the M40i trim, restoring the Z4’s stronger performance identity.

The bottom line: If you want the Z4 with its most compelling engine story and a stable used-car market, the 2020 is the one to target. If you’re more price-sensitive, the sDrive30i can still give you the core roadster experience, but you should be selective about condition and equipment so you don’t give up too much of what makes the Z4 special.
