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 93 listings available, which suggests a relatively limited pool of used examples to choose from.

Is the 2020 BMW Z4 a good car?

Yes — the 2020 BMW Z4 earns a 4.71/5 user rating and a 7.5/10 expert rating. The standout strength is Performance at 9/10.

Owners consistently praise its performance, handling, comfortable seats, and smooth transmission. The Z4 also fits buyers who want a small luxury roadster with serious punch and a strong driving focus.

The main trade-offs are its outdated technology and some road noise from the soft top, so you should expect the experience to lean more toward driving enjoyment than cutting-edge convenience.

Only 37.6% of listings are priced as good or great deals, so the market still rewards shoppers who move quickly on the right car.

Is the 2020 BMW Z4 reliable?

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

User feedback points to a car that feels dependable in the ways that matter most to enthusiasts: strong performance, smooth operation, and a driving experience owners are happy to live with over time. The expert evaluation also describes the Z4 as a well-sorted roadster with a refined powertrain and a polished overall character.

The cost-effectiveness review also frames the Z4 as a strong value relative to similarly capable roadsters, which can help reduce the risk of buyer’s remorse if you plan to keep it long term.

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

Accident-free inventory is solid at 76.3% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not replace a proper records review. Prioritize a pre-purchase inspection that focuses on the roof mechanism, electronics, and signs of hard use, since those are the kinds of areas that can matter most on a used roadster. It also makes sense to pay close attention to overall condition, because the best examples will usually show careful ownership and lighter wear.

Key things to evaluate:

• Trim level: The base sDrive30i comes with automatic LED headlights, rain-sensing wipers, auto-dimming mirrors, automatic climate control, a 10.24-inch touchscreen, navigation, HD Radio, and Apple CarPlay, but Android Auto is missing. The M40i adds the inline-6 and includes more equipment, making it the better fit if you want the stronger performance identity and a more fully equipped roadster.
• Powertrain: The sDrive30i uses a 2.0-liter turbocharged 4-cylinder with 255 horsepower and 295 pound-feet of torque, while the M40i uses a 3.0-liter turbocharged inline-6 with 382 hp and 368 lb-ft. The 4-cylinder is quick and eager, but the inline-6 is the one that restores the Z4’s serious punch.
• Safety package: Standard safety 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’s iDrive system and a virtual instrument panel. Apple CarPlay is offered, but Android Auto is missing, and the tech review notes that switching between screens is not especially intuitive.
• Fuel efficiency: No fuel-economy figure is stated in the provided data.

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 entry point and the best-value choice if you want the Z4 experience at the lowest starting price. You still get the core roadster formula, a turbocharged 4-cylinder, and a well-equipped cabin, but you’ll want to budget for options if you care about more luxury or driver-assistance features.
• sDriveM40i: This is the trim to buy if you want the Z4’s defining character at its strongest. It brings the inline-6 back, adds the Track Handling package equipment, and delivers the performance that makes this model year stand out.

The safety package is optional rather than fully standard, so check each listing carefully for the driver-assistance equipment you want.

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

This is a moderate, selective-buyer market, so you can shop patiently but should act fast when a strong listing appears.

• Deal availability: 37.6% of listings are priced as good or great deals.
• Inventory: There are 93 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 76.3% 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 $36,453 sits slightly below last year's $36,628.

That small decline suggests the Z4 has been holding value fairly steadily rather than swinging sharply in either direction. For a future seller, that kind of price stability can be helpful because it points to a market that is still willing to pay for the car’s mix of performance and premium appeal.

The limited inventory also supports resale strength, since fewer examples on the market can help keep demand focused on well-kept cars. If your Z4 is clean, well-optioned, and documented, it should be easier to position it competitively when you decide to sell.

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 the Driving Assistance package adds blind-spot monitoring and lane-departure warning. The Convenience package adds rear cross-traffic alert, automatic parking, satellite radio, adaptive cruise, and smartphone key pairing.

The safety review also notes relatively poor rear visibility with the top up, and the wind deflector can make rearward visibility more difficult with the top down.

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:

• 37.6% of listings are priced as good or great deals.
• Accident-free inventory is solid at 76.3% — always verify the vehicle history report.
• 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 the most compelling performance story, the 2020 model year is the one to target because it brings back the inline-6 and keeps pricing relatively stable. If you’re more price-sensitive, the nearby years can still make sense, but you should compare equipment closely and focus on the cleanest, best-documented example you can find.
