The B-Class is easy to overlook because it does not sell the same image as a CLA or GLA. For the right buyer, that is exactly its strength. A higher roof, easier access and practical cabin can matter more than a low coupé-style roofline. The W246 and W247 both follow that logic, but the W247 brings a newer Mercedes interior and more digital technology.
A used B-Class should therefore be bought around everyday usability. Sit in it, load it, park it and test the electronics. If those basics fit your routine, the model can be a more rational Mercedes than a more fashionable alternative.
W246 vs W247 at a glance
| Factor | W246 | W247 |
|---|---|---|
| Main advantage | Lower purchase price and conventional controls | Newer cabin, technology and assistance features |
| Best for | Value-focused practical buyers | Drivers who want practicality without an old-feeling interior |
| Key inspection focus | Age, history, tyres and chassis wear | Electronics, exact options and condition |
Why buyers choose a B-Class
The important advantages are ordinary but useful: getting in and out, fitting child seats, carrying taller items and having a more upright seating position. If an older relative uses the car regularly, test access with that person. A specification sheet cannot tell you whether the seat height and door opening are comfortable.
W246: a value-first decision
The W246 can be attractive when you want a practical Mercedes without spending heavily on the newest interior. As these cars age, inspect service history carefully and budget for normal age-related work. Look at the dates on tyres and the battery, not only tread depth and whether the engine starts.
Check the rear seats, folding mechanisms and luggage area for signs of hard family use. Scratches are cosmetic; broken latches, water entry and damaged seat mechanisms affect usefulness.
W247: newer cabin, more to verify
The W247 modernises the driver environment substantially. This can make it feel far newer than the W246 even when the core job is similar. Verify the exact screen, camera, lighting, seat and assistance specification before comparing prices.
Spend time using the interface. Some buyers prefer the newer digital layout; others may value the W246’s simpler physical interaction. The better generation is the one you enjoy using every day, not the one a brochure says is newer.
Family-use inspection checklist
- Fit the actual child seat and check access around it.
- Fold and raise every rear-seat section.
- Inspect boot floor, seals and spare-wheel or repair-kit area for moisture.
- Test rear vents, charging points and window operation.
- Check doors for smooth opening, closing and central locking.
- Look for uneven tyre wear from repeated kerb impacts or alignment issues.
Road test
Start from cold, then drive in the environment where the car will actually live. Include parking-speed manoeuvres, rough urban roads and a higher-speed section. Listen for suspension noise and check that the transmission behaves consistently when cold and warm. Test the air-conditioning at idle as well as while driving.
B-Class or GLA?
If you want practicality but also prefer SUV styling and a higher visual driving position, compare the GLA. The X156 vs H247 GLA guide explains how the two GLA generations differ. If cabin usefulness matters more than appearance, do not assume the GLA is automatically the better family car.
Verdict
The W246 is a sensible value choice when history is strong and you are comfortable with older multimedia. The W247 is easier to justify when the newer interior and assistance technology are important to you. Neither needs to be exciting to be a good purchase; it needs to make everyday life easier.

Questions buyers ask about W246 and W247
Why choose B-Class instead of A-Class?
The B-Class makes sense when entry height, rear-seat access and cabin versatility matter more than a lower roofline. Try both cars back to back. The better choice becomes obvious when you fit child seats, carry older passengers or load bulky items.
Is W247 worth paying more for?
It can be if the newer digital cabin and assistance equipment improve your daily use. Do not pay simply because it is the newer chassis code. Compare actual equipment, service history and first-year costs.
What should a family buyer check that a normal road test misses?
Rear door opening, seat-folding mechanisms, boot floor condition, charging ports, rear vents and water sealing. Also check whether your preferred child seat blocks front-seat travel or access to seat-belt buckles.
Can an older W246 be the better long-term car?
Yes, when it has strong maintenance evidence and the simpler cabin suits you. Age still matters, so inspect tyres, battery, suspension and air-conditioning carefully.
What should make me reject either generation?
Unexplained warning lights, a seller who prevents independent inspection, inconsistent VIN or documents, serious corrosion or poorly repaired structural damage are stronger reasons to walk away than cosmetic wear.
