The Mercedes-Benz GLB was offered with both petrol and diesel engine options in India, paired with automatic transmissions. The petrol variant typically featured a 1.3-litre turbocharged engine (GLB 200) producing around 163 hp and 250 Nm of torque, mated to a 7-speed DCT. The diesel variants (GLB 220d) came with a 2.0-litre unit producing around 190 hp and 400 Nm of torque, paired with an 8-speed automatic transmission, with some offering 4MATIC all-wheel drive.

When considering a used GLB, listen for any unusual engine noises, such as excessive knocking or rattling, which could indicate underlying issues. Inspect for any visible oil or coolant leaks, particularly around the engine bay and underneath the vehicle. Test the automatic transmission for smooth and responsive gear changes; any jerking, hesitation, or delayed shifts could point to problems with the dual-clutch transmission (DCT) or the conventional automatic. A comprehensive service history from authorised Mercedes-Benz service centres or reputable specialists is crucial for a luxury vehicle. Look for evidence of regular oil changes and adherence to the manufacturer's maintenance schedule.

Ride and Handling

The Mercedes-Benz GLB offered a ride and handling balance that leaned towards comfort and stability, suitable for a family SUV. It featured a sophisticated suspension setup designed to absorb road imperfections effectively, providing a composed ride. While generally smooth, models with larger wheels or AMG Line trims could exhibit a firmer ride.

When assessing a used GLB, listen for any knocking or creaking noises from the suspension, especially over bumps, which could indicate worn bushings, struts, or mounts. Inspect for any fluid leaks from shock absorbers. Ensure the steering feels precise and responsive, without excessive play or unusual noises. Uneven tyre wear can be a sign of alignment problems, which might require attention. Check for any shuddering or pulsing during braking, which could indicate warped brake rotors. Test the vehicle at various speeds to assess its stability and ride comfort, noting any excessive body roll or floatiness.

The interior of the Mercedes-Benz GLB offers a premium and technologically advanced cabin, balancing luxury with practicality, especially with its unique 7-seater layout. It features high-quality materials, including soft-touch plastics, leather upholstery, and metallic accents, all contributing to a sophisticated ambiance. The MBUX infotainment system is a central feature, presented across dual digital screens.

When evaluating a used GLB, carefully inspect the upholstery for excessive wear, tears, or stains, particularly in the third row if it has seen frequent use. Test all electronic features thoroughly, including the MBUX infotainment system for responsiveness, Bluetooth and Apple CarPlay/Android Auto connectivity, and the functionality of all power-operated features like windows, seats, and the panoramic sunroof (if equipped). Pay attention to any interior rattles, especially from the rear third-row seats or dashboard trim, as these have been reported by some owners. Ensure all climate control functions work correctly across all zones. Lastly, check for any unusual odours that might suggest water leaks or mould, particularly around the sunroof seals.

Infotainment

The Mercedes-Benz GLB features the advanced MBUX (Mercedes-Benz User Experience) infotainment system, which was a significant highlight of its cabin. This system typically includes a 10.25-inch digital instrument cluster and a matching 10.25-inch central touchscreen display, providing a seamless digital experience. The MBUX system is known for its intuitive interface, voice control ("Hey Mercedes"), and smartphone integration.

When inspecting a used model, verify the responsiveness and clarity of both digital screens. Check for any frozen screens, glitches, or connectivity issues with Bluetooth or smartphone mirroring. Test the voice command system to ensure it functions as expected. If the car has integrated navigation, verify its accuracy and update status. For models equipped with a premium sound system, test all speakers for clear audio and absence of distortion. It is also advisable to inquire about any pending software updates for the MBUX system, as these can often resolve minor bugs and improve overall performance.

The exterior design of the Mercedes-Benz GLB stands out with its rugged and boxy aesthetic, often described as a "baby GLS" due to its resemblance to Mercedes-Benz's flagship SUV. This design language gives it a more utilitarian and robust appeal compared to its curvier stablemates. It features a prominent grille, distinctive LED headlights, and a purposeful stance.

When considering a used GLB, it is important to inspect the bodywork for any signs of accident damage, such as inconsistent panel gaps or mismatched paint, as luxury vehicles are expected to maintain a pristine appearance. Check for stone chips, scratches, and dings, particularly on the lower body cladding, which can indicate rough use. Ensure all exterior lights, including LED elements, are fully functional, as repairs can be costly. Also, examine the alloy wheels for curb rash and ensure the tyres are of a reputable brand with even wear, as uneven wear might suggest alignment issues or suspension problems.

Safety in the Mercedes-Benz GLB was a strong point, with the global model receiving a 5-star Euro NCAP safety rating. It came equipped with a robust passive safety structure and a comprehensive array of active safety features. These typically included multiple airbags (up to 7 airbags), ABS with EBD, Electronic Stability Program (ESP), and Traction Control. Higher variants also offered advanced driver-assistance systems (ADAS).

When inspecting a used GLB, ensure that no airbag warning lights or other safety system fault indicators are illuminated on the dashboard. Check the condition of brake pads and rotors, and listen for any unusual noises during braking. If the car is equipped with ADAS features like Active Brake Assist, Lane Keeping Assist, or Blind Spot Assist, test their functionality where possible and ensure no sensor errors are present. A 360-degree camera system and parking sensors should also be checked for proper operation, as these are vital for parking a larger SUV.

As a discontinued model, the used Mercedes-Benz GLB competes with both new and used luxury SUVs in India, particularly those offering a blend of premium features and practicality.

New competitors include the new Audi Q3 and new BMW X1, which are premium compact SUVs, though they typically offer 5-seater configurations. The new Hyundai Alcazar and new Tata Safari are more affordable 7-seater SUVs that compete on practicality and features, albeit without the luxury badge.

On the used market, the GLB competes with used Mercedes-Benz GLC (which was often preferred by buyers due to its positioning), used BMW X1, and used Audi Q3. It also competes with used Land Rover Discovery Sport, another luxury SUV that offered 7-seater capability. The used GLB offers the advantage of a Mercedes-Benz badge and 7-seater practicality at a significantly lower price point than new luxury SUVs. However, it lacks a new car warranty, and maintenance costs for a luxury vehicle can be substantial.

The Mercedes-Benz GLB, now a discontinued model from 2025, transitions into a compelling option in the used luxury SUV market in India. It successfully offered a unique combination of Mercedes-Benz luxury, a distinctive rugged design, and the rare advantage of a 7-seater configuration in its compact class. On the used market, it provides an opportunity to own a premium family SUV at a more accessible price point than its original new cost.

However, potential buyers must be prepared for the realities of owning a used luxury vehicle. This includes potentially higher maintenance and repair costs, especially for complex electronic systems (like MBUX glitches or sensor faults) and transmission components (DCT hesitation).
