The MERCEDES-BENZ GLB (2019-24) is a premium compact SUV, positioned between the GLA and GLC in Mercedes-Benz’s UK range. Its upright shape prioritises space over a coupe-like look, and selected versions offer seven seats, a rare feature among rivals. It suits families wanting flexibility without a large SUV, plus commuters seeking a comfortable, upmarket everyday car. mycarcheck.com records 7,032 checks across 4,191 distinct GLB VINs, a strong sample of used-car interest. The average private-sale valuation was £29,500, while average recorded mileage was 32,000 miles and annual mileage 9,000. Checks show an average of 0.62 previous keepers, so many examples have had relatively few owners. Against the BMW X1, Audi Q3 and Volvo XC40, the GLB stands out for its versatile layout. Its cabin suits daily use, while petrol and diesel options broaden its appeal. For used buyers it pairs Mercedes style with family practicality; inspect each car’s history and condition.
