How much does the 2020 Mercedes-Benz GLB cost?

Prices have softened 12.41% compared to this time last year, making it a favorable time to shop this model year.

There are 521 listings available, which suggests you have a workable amount of inventory to compare.

Is the 2020 Mercedes-Benz GLB a good car?

Generally — the 2020 Mercedes-Benz GLB earns a 4.14/5 user rating and an 8.5/10 expert rating. The model scores 10/10 across Form and function, Technology, and Safety.

Owners consistently praise its great design, premium features, and versatility, and many also like its comfortable size. The GLB’s practical, utility-first approach fits shoppers who want a premium-feeling small SUV that emphasizes everyday usefulness over flash.

The main trade-offs are a ride that can feel a bit rough and some questions about interior materials. The expert review also notes that the brakes are lacking and that desirable features can push the price up significantly.

That mix makes the GLB especially appealing if you value space, tech, and a distinctive Mercedes-Benz feel more than outright performance. Good and great deals account for 38.4% of listings, which gives you some room to shop selectively.

Is the 2020 Mercedes-Benz GLB reliable?

Owners rate it 4.14/5, a solid signal of long-term satisfaction.

The owner summary points to a vehicle that feels dependable in daily use, with praise centered on its premium features, versatility, and comfortable size. It also suggests the GLB is the kind of SUV many owners feel good about living with over time.

The expert review reinforces that impression by describing the GLB as practical and enjoyable to drive, with technology that works well and a cabin that feels thoughtfully executed. The cost-effectiveness review also notes that utility is a strength, which matters when you’re thinking about long-term ownership value.

For used buyers, the main long-term risk is that the GLB’s desirable options can make repairs and upkeep more expensive if the vehicle was heavily optioned or poorly maintained.

What should I look for when buying a used 2020 Mercedes-Benz GLB?

Accident-free inventory is solid at 80.6% — 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 brakes, ride quality, and interior condition, since those are the areas most likely to affect your satisfaction. It also makes sense to confirm which desirable options are actually installed, because the GLB’s price can rise quickly with equipment.

Key things to evaluate:

• Trim level: The GLB 250 is the standard model, and the GLB 250 4Matic adds all-wheel drive. The base setup is practical and well equipped, while the 4Matic version is the better fit if you want extra traction and the more complete version of the GLB’s capability.
• Powertrain: Both trims use a turbocharged 2.0-liter four-cylinder engine with 221 horsepower and 258 lb-ft of torque, paired with an eight-speed dual-clutch automatic transmission. The available 4Matic system sends power rearward as needed, and an Off-Road driving mode locks in a 50:50 split for maximum traction.
• Safety package: The standard safety suite includes a driver monitoring system, a backup camera, forward collision warning with pedestrian detection, automatic emergency braking, and Pre-Safe front collision preparation. The optional Driver Assistance Package adds adaptive cruise control, lane-centering assistance, evasive steering assistance, automatic emergency stop assistance, and additional Pre-Safe enhancements.
• Infotainment: The standard setup uses a 7-inch infotainment and instrumentation display, while the Premium Package upgrades to twin 10.25-inch screens under one piece of glass. The system includes Android Auto, Apple CarPlay, and natural voice recognition, and navigation with augmented video is available with the Multimedia Package.
• Fuel efficiency: The expert test drive returned 21.4 mpg, and the review notes that this fell short of the expected 26-mpg estimate.

Which 2020 Mercedes-Benz GLB trim should I buy?

The 2020 Mercedes-Benz GLB is offered in 2 trim levels: GLB 250 and GLB 250 4Matic.

Here's the short version:

• GLB 250: This is the entry point, and it makes the most sense if you want the GLB’s core strengths at the lowest price. You still get the turbocharged 2.0-liter engine, the practical cabin, and the premium Mercedes feel, but you’ll want to be selective with options because the desirable equipment can add up quickly.
• GLB 250 4Matic: This is the better choice if you want all-wheel drive and a more confidence-inspiring setup for mixed weather or rougher conditions. It keeps the same engine and overall character, but the added traction makes it the more versatile pick for many shoppers.

For safety, the standard equipment is strong, but the optional Driver Assistance Package adds the most advanced driver aids.

Is now a good time to buy a used 2020 Mercedes-Benz GLB?

This is a moderate market for selective buyers, so it pays to compare listings carefully and move quickly on strong examples.

• Deal availability: 38.4% of listings are priced as good or great deals.
• Inventory: There are 521 listings available.
• Price trend: Prices have softened 12.41% compared with last year.
• Clean inventory: 80.6% of listings are accident-free.

If you find a listing below $20,162, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Mercedes-Benz GLB's resale value?

The current average of $20,162 sits slightly below last year's $23,019.

That decline suggests the GLB has become more affordable for buyers, which can help you if you’re shopping now. For a future seller, though, it means you should expect resale pricing to reflect the softer market unless your vehicle is especially clean, well equipped, and well documented.

The GLB’s practical appeal and premium badge should help it stay relevant with used shoppers who want utility and luxury in one package. Strong condition and desirable equipment will matter more if you want to protect value later.

Vehicles with solid owner satisfaction ratings, like this model year's 4.14/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 Mercedes-Benz GLB safe?

The 2020 Mercedes-Benz GLB had not been crash tested by NHTSA or IIHS when this review was published.

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

Standard safety equipment includes a driver monitoring system, a backup camera, forward collision warning with pedestrian detection, automatic emergency braking, and Pre-Safe front collision preparation. Emergency call service is also standard and remains free for as long as you own the GLB.

The optional Driver Assistance Package adds adaptive cruise control, lane-centering assistance, evasive steering assistance, automatic emergency stop assistance, and extra Pre-Safe enhancements. Second-row side-impact airbags and blind-spot monitoring with Exit Warning Assist are also available.

The main caveat is that many of the most advanced safety features are optional rather than standard, so you’ll want to confirm whether a used example has the package you want.

Should I buy a 2020 Mercedes-Benz GLB 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:

• 38.4% of listings are priced as good or great deals.
• Accident-free inventory is solid at 80.6% — always verify the vehicle history report.
• Price trend: Prices have softened 12.41% compared with last year.
• Owners rate it 4.14/5 — a solid satisfaction signal.
• It emphasizes utility and practicality over style and performance.

Consider the 2021 if:

• At $23,039, the 2021 costs more than the current year's $20,162 average.
• It adds an optional third row for seven-passenger seating.

The bottom line: If you want the better value today, the 2020 is the smarter buy because pricing has softened and inventory is healthy. If you need extra seating and can spend more, the 2021 is the better fit.
