The GLA and GLB are actually very similar cars, built on the same NGCC (New Generation Compact Class) chassis which was also used for the A-Class , B-Class , and CLA . The GLA is the smaller of the two models, and while it’s still an SUV, it gets a more compact, hatchback-like shape. The GLB is larger, more square-shaped, has more interior space, and has the option of seven seats. The GLC is a larger, much more expensive model, which shares no parts with the GLA or GLB, and is actually based on the same chassis as the C-Class saloon .

Used Mercedes-Benz GLB pros and cons

Boxy styling looks superb
Entry-level cars lack kit
Comfortable to drive
Engine choice isn't huge
Plush cabin and great infotainment
Alternatives have bigger boots and rear seats

Is a used Mercedes-Benz GLB a good car?

The Mercedes GLB is a middle-sized family SUV, with optional seats for seven, and boxy styling that makes it feel like buying a set of chunky Timberland boots just for walking to the shops.

The GLB manages to look quite imposing, thanks to that boxy styling and the massive grille at the front. Inside, the GLB’s cabin is as posh as the exterior, with a big digital dashboard and mostly decent materials.

There’s lots of space, and tonnes of storage in the centre console, but the extra seats in the boot — and they were optional, not standard — aren’t very big.

The GLB really stars when you drive it around town, where it’s easy to fit into tight spaces. The excellent ride comfort easily deals with the worst in-town bumps and lumps too.

There are alternatives that are cheaper and more spacious inside, but little else in the seven-seat family SUV market that has quite the premium-class clout of the Mercedes badge.

What to look for when buying a used Mercedes-Benz GLB

The Mercedes GLB didn’t place in the 2024 Driver Power Top 50 Cars To Own survey, but Mercedes as a brand finished in a pretty poor 25th place out of 32 brands in the customer satisfaction survey, with a high 26% of owners reporting problems, and a very poor mark for reliability and quality.

The GLB is generally thought to be a solidly built car though, with few reported reliability issues, but Mercedes still has some work to do to convince that it’s back to its imperious best in quality terms.
