What Do the Reviews Say?

The Mercedes Benz GLB focuses on convenience and luxury rather than performance.

The vehicle has a discretionary adaptive suspension that tightens the handling on demand, but it is far from a perfect SUV. 

Meanwhile, let’s hear what the reviews have to say.

The 2023 GLB is a good luxury compact SUV. It boasts an upscale cabin, a long list of features, a comfortable ride, and an available AMG model. Its boxy shape also helps make it a versatile option that can handle a variety of storage demands. A somewhat finicky infotainment system and cramped optional third-row seats are minor flaws, but they shouldn’t prevent you from buying this Mercedes.

With two decent engine options, including a 302-horsepower AMG variant, this Mercedes combines a composed drive with luxury trimmings for a nice overall package.
