Good small SUV, the 220d engine felt correct for the car. Interior fittings more SUV than limo., but liveable. Did not buy as rear seats are too hard for my intended use.

I only had a short test drive, but the car is very comfortable, spacious and ultra modern inside. It drives well and is quiet and refined. If your looking for a smallish 7 seater, it needs to be on your list.

Mercedes-Benz GLB-Class (2019-2025) Pros and Cons
| Pros | Cons |
|---|---|
| Impressive practicality and space | Not especially engaging to drive |
| Seven seats when most rivals have five | Third-row seats are best suited to children |
| Excellent MBUX infotainment system | Versions on larger wheels have a firm ride |
Quick Summary
The Mercedes-Benz GLB-Class (2019-2025) is a premium compact SUV that prioritises practicality over fashion. Based on the same underpinnings as the A-Class and B-Class, the GLB combines relatively compact dimensions with a surprisingly spacious cabin. Its tall, upright and deliberately boxy design stands out in the premium compact SUV market, particularly because it offers the option of seven seats – something still relatively unusual at this size and price point. All later versions come with seven seats as standard, making it more versatile than rivals like the Audi Q3 and BMW X1.
The GLB excels in practicality, with five-seat versions offering 570 litres of boot space, expanding to 1,805 litres with rear seats folded. Rear-seat room is impressive, and large rear doors make fitting child seats easier than in coupe-inspired alternatives. The impressive MBUX infotainment system features dual 10.25-inch widescreen displays, highly configurable and operable via touchscreen, steering wheel controls or touchpad. Engine performance is adequate across the range, with diesel models particularly well-suited to motorway driving. Running costs are reasonable for a seven-seat SUV, with the GLB 200d capable of returning around 50mpg. The Mercedes-AMG GLB 35 4Matic variant offers over 300bhp for those seeking more performance.
Best for: Family buyers seeking seven-seat practicality, those prioritising space and visibility over sporty handling, and buyers wanting premium ambiance with genuine versatility.
Not ideal for: Drivers seeking an engaging, sporty drive, those wanting a coupe-like aesthetic, or buyers on a tight budget seeking lower running costs than premium rivals.

| BMW X1 | 4/5 | 4.5/5 | 39.2% | 4.4/5 |
The Verdict
You should buy the GLB-Class if: You're a family buyer seeking seven-seat practicality, prioritising space and visibility over sporty handling, or wanting premium ambiance with genuine versatility.
Consider alternatives if: You seek an engaging, sporty drive, prefer a coupe-like aesthetic, or require lower running costs than premium rivals.
Competitive Position: The Mercedes-Benz GLB-Class is a standout choice in the premium compact SUV segment, offering seven-seat practicality that most rivals cannot match. Whilst the Land Rover Discovery Sport offers slightly higher user ratings and the BMW X1 provides a more engaging drive, the GLB's focus on space, visibility and premium ambiance makes it the most practical choice for family buyers. Its excellent MBUX infotainment system and strong safety credentials further enhance its appeal. The GLB scores particularly well on value, with 53.5% of available listings representing good or great deals – significantly higher than competitors like the Audi Q3 and BMW X1.
