The 2021 Mercedes-Benz GLB-Class is a compact, seven-passenger (optional) SUV that slots between the GLA and GLC in Mercedes' lineup. Introduced for the 2020 model year, it offers a boxier, more practical alternative to its sleeker siblings. Key trims include the GLB 250 and AMG GLB 35. Its popularity stems from its combination of Mercedes luxury, available third-row seating, and relatively affordable pricing, generally ranging from $38,000 to $55,000.
The Good
The 2021 GLB-Class offers a compelling blend of practicality and luxury. Its boxy design maximizes interior space, appealing to practical buyers needing cargo room or the optional third row. The Mercedes badge and available upscale features provide emotional appeal, while decent fuel efficiency and a comfortable ride enhance its value proposition.
The Bad
The 2021 GLB-Class, while appealing, has potential drawbacks. The optional third-row seating is cramped and best suited for children. The base engine can feel underpowered when fully loaded. Some owners have reported issues with the MBUX infotainment system. Be mindful of potential repair costs associated with a luxury brand.

Final Verdict: Is the 2021 Mercedes-Benz GLB-Class a Good Sport Utility Vehicle?
The 2021 Mercedes-Benz GLB-Class is ideal for buyers seeking a compact luxury SUV with a practical design and optional third-row seating (for small children).

A used GLB 250 in good condition with reasonable mileage can represent decent value.
Consider the AMG GLB 35 if you prioritize performance. Thoroughly inspect any potential purchase and ensure all recalls have been addressed. Factor in the cost of an extended warranty for added peace of mind, particularly with the MBUX system.
