Used 2020 BMW Z4 for Sale nearLos Angeles, CA

Is the 2020 BMW Z4 a good car?

Yes — the 2020 BMW Z4 earns a 4.7/5 user rating and a 7.5/10 expert rating. The standout strength is Performance at 9/10. Owners consistently praise its performance and handling, and they also highlight the comfortable seats, smooth transmission, and powerful engine. On the downside, the expert review calls out outdated technology, and the overview frames this Z4 as a car for you if you want a compact convertible that feels lively and engaging rather than merely stylish. With 44.3% of listings priced as good or great deals, you have a decent chance of finding a competitive offer.

Is the 2020 BMW Z4 reliable?

Owners rate it 4.7/5, a strong signal of long-term satisfaction. The owner summary points to a car that feels dependable in daily use, with praise centered on its smooth transmission, strong performance, and comfortable seating. The performance notes also describe the powertrain as eager and well sorted, which supports the impression that this is a car you can count on for enjoyable driving over time. For used buyers, the main long-term ownership risk is that a sporty roadster can be more sensitive to maintenance history and prior use, so condition matters a lot.

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

At 74.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important. You should start with a vehicle history report, then prioritize a pre-purchase inspection that focuses on bodywork quality, roof operation, and signs of hard use. Because this is a low-slung convertible with performance intent, you should also pay close attention to how the car drives at speed, how the cabin electronics behave, and whether any prior damage affected fit and finish.

Key things to evaluate:

• Trim level: The base sDrive30i brings automatic LED headlights, rain-sensing wipers, auto-dimming mirrors, automatic climate control, a 10.24-inch touchscreen, navigation, HD Radio, and 20GB of storage, but it does not include Android Auto. The sDriveM40i adds 19-inch alloys with non-run-flat tires and includes more of the performance-oriented equipment, making it the better fit if you want the stronger roadster character.
• Powertrain: The sDrive30i uses a 2.0-liter turbocharged four-cylinder with 255 hp and 295 lb-ft of torque, while the sDriveM40i uses a 3.0-liter turbocharged inline-six with 382 hp and 368 lb-ft of torque. The four-cylinder is lighter and can feel a bit sharper, but the inline-six is the one that delivers the stronger performance identity this Z4 is known for.
• 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, an automatic parking system, satellite radio, adaptive cruise, and smartphone key pairing.
• Infotainment: The Z4 uses a 10.24-inch touchscreen with BMW iDrive, and Apple CarPlay is offered, but Android Auto is missing. The system also includes navigation and HD Radio, and the car can be equipped with wireless charging and a Wi-Fi hotspot through packages.
• Fuel efficiency: The 2.0-liter engine can get to 60 mph in about 5.5 seconds, and the performance notes emphasize that it is the lighter, more efficient-feeling choice in the lineup.

Which 2020 BMW Z4 trim should I buy?

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

Here's the short version:

• sDrive30i: This is the value play if you want the Z4 experience at the lower starting price. You still get the core luxury and tech features, plus the 255-hp turbo four-cylinder, and it can be optioned with the Track Handling package if you want sharper dynamics without jumping to the six-cylinder model.
• sDriveM40i: This is the one to buy if you want the Z4’s full personality. It brings the 3.0-liter inline-six, more standard performance hardware, and the strongest acceleration and character in the lineup, making it the best choice for buyers who care most about the car’s driving feel.

The safety package is a meaningful consideration here: the Driving Assistance package adds blind-spot monitoring and lane-departure warning, while the Convenience package adds rear cross-traffic alert and adaptive cruise.

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. 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. The review also notes relatively poor rear visibility when the top is up, which is worth keeping in mind if you plan to use the car in tight spaces.

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:

• 44.3% of listings are priced as good or great deals.
• At 74.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Owners rate it 4.7/5 — a strong satisfaction signal.
• The 2020 model year is the one that brings the inline 6-cylinder engine back to the Z4 lineup in M40i form, restoring the stronger performance identity this roadster is known for.

The bottom line: If you want the Z4 with the strongest performance identity and a favorable market, the 2020 is the right year to target. If you’re shopping more on price, the 2019 and 2021 nearby years can still be worth comparing, but the 2020 stands out for bringing back the six-cylinder engine while keeping the car’s sharp handling and open-top appeal.
