Why it stands out
The 2021 Mercedes-Benz GLB stands out for its versatility and family-friendly features, offering an optional third row that can accommodate up to seven passengers. Its attractive pricing starts at $38,050 for the GLB 250 FWD, making it an appealing entry point into the Mercedes-Benz brand. The interior design is modern and well-crafted, with excellent fit and finish that reflects the brand's luxury status. Notably, the GLB also boasts an impressive technology suite, featuring the latest MBUX infotainment system with voice control.
