Second Hand Mercedes-Benz B-Class Roof Rack

The B-Class does not come with a factory-fitted roof rack as standard, but Mercedes-Benz designed the roof with integrated mounting points (roof rails or flush rail slots) on certain trims, allowing aftermarket or genuine Mercedes roof racks to be fitted as an accessory. This means what you are looking for from a breaker is almost certainly a set of roof rails or a complete roof rack system removed from another B-Class, rather than a factory-standard component. Confirm with the breaker whether the car they are breaking has the rails or rack fitted, as not every B-Class will.

No — the W245 (2005–2011) and W246 (2012–2018) are completely different platforms with different roof dimensions, rail positions, and roof profiles, so roof rack components are not interchangeable between the two generations. Always source a roof rack that matches your specific generation: W245 for 2005–2011 cars, W246 for 2012–2018 cars. Confirm the exact part with the breaker against your registration to be certain.

The W246 received a facelift around 2015, but roof structure and rail mounting points are generally not affected by mid-generation facelifts of this type. In practice, a roof rack or roof rails from a pre-facelift W246 (2012–2014) are likely to be compatible with a post-facelift W246 (2015–2018), as the roof pressing and mounting points typically remained the same. That said, whether a specific rack or rail set crosses this boundary without issue is something you should confirm with the breaker against your registration before purchasing.

Trim level — whether SE, Sport, or AMG Line — does not affect the roof structure or mounting point positions on the B-Class, so fitment is the same across trims within the same generation. What may differ cosmetically is whether a car left the factory with roof rails already fitted, as rails were standard on some trims and optional on others, so a rack from an AMG Line car will fit an SE of the same generation just as well. Bear in mind any colour or finish differences if aesthetics matter to you, and confirm the exact fitment with the breaker.

The A-Class and B-Class are related but are distinct body styles — the A-Class is a hatchback and the B-Class is a taller MPV-style five-door — so their roof dimensions, profiles, and rail mounting points differ and parts are not directly interchangeable. Always source a roof rack specifically listed for the B-Class and the correct generation (W245 or W246) rather than assuming A-Class parts will cross over. Confirm compatibility with the breaker against your registration before buying.

Give the breaker your registration number so they can confirm your exact generation (W245 2005–2011 or W246 2012–2018), and ask whether the car they are breaking actually has roof rails or a rack fitted, since not all B-Class cars left the factory with them. Engine and trim level will not affect fitment, so you do not need to worry about those details. The key things are generation and whether the donor car has the relevant mounting hardware included.
