Why it stands out
The 2020 Mercedes-Benz GLB distinguishes itself in the small luxury SUV segment through a blend of practicality and thoughtful design. Sitting on a front-wheel-drive platform, the GLB offers an optional third row of seats, which is rare for its class, accommodating up to seven passengers. This feature, combined with excellent interior space utilization, outshines its larger priced rivals like the GLC. The SUV's premium tech includes the Mercedes Benz User Experience (MBUX) infotainment system, which is praised for its responsive interface and natural voice recognition capabilities. Furthermore, its turbocharged 2.0-liter engine produces a respectable 221 horsepower, providing a balanced combination of performance and comfort. However, the GLB does have some downsides, such as a relatively lacking braking performance and an interior that may not match the luxury expectations associated with the brand due to some cost-cutting in materials. Overall, the GLB is a compelling choice for buyers seeking versatility and modern features without stepping into a pricier segment.

I absolutely love this vehicle. It is a great value for the money. The features are amazing and it is the perfect size for me. It is just for me. I am retired and I dont have any small children so I dont need anything big and I dont want anything too small. It is the perfect size with the perfect amount of features.
