The MERCEDES-BENZ GLB (2023-) is a premium compact SUV, positioned between small crossovers and larger seven-seat models in the UK market. Its upright shape creates a roomy, practical feel, and some versions add a rare third row. It suits families wanting flexibility without a full-size SUV. Mycarcheck.com has recorded 1,196 checks across 820 distinct VINs, providing a useful snapshot of interest. Average private-sale valuation is £34,800, with average recorded mileage of 13,000 miles. The average previous-keeper figure is 0.16, reflecting the model’s recent arrival and many nearly new examples. Treat these figures as guides, not guarantees. The GLB suits school runs, commuting and family trips, with a comfortable cabin and raised driving position for everyday family use. Against rivals such as the BMW X1 and Audi Q3, its boxier styling and optional seven-seat layout stand out.
