Looking at a B Class?

Population figures cannot tell you whether one particular car is taxed, MOT-valid or safe to buy.

Check its registration free for the official tax, MOT and mileage record. If the car is still worth pursuing, the optional £9.99 full history check adds outstanding-finance, stolen and insurance write-off checks.

Wondering whether one particular B Class is off the road? A free SORN check shows whether it is currently SORN, taxed or untaxed.

Is the B Class disappearing?

Licensed numbers peaked at 76,181 in 2022 Q2 and stand at 68,153 in 2026 Q1, down 11%. That is down 10% in the five years since 2021 Q1. A further 3,261 are declared SORN — 1 in 22 of the 71,414 still on the DVLA record is off the road, laid up, part-restored or waiting to be sold.

A falling population is worth knowing before you buy: it usually means fewer donor cars, fewer specialists and slower parts supply, and it is why a good example of a scarce model can hold its price while a neglected one is hard to sell at any price.

B Class MOT pass rate

In 2024, 70.1% of 56,323 Mercedes B Class MOTs passed first time — below the 71.2% UK average. Pass rate moves with age: 87.8% of cars aged 3–5 years passed first time, against 55.5% aged 15–30 years.

  • Condition — 5.7% of tests. Corrosion, damage or wear on a tested component. Worth seeing in person, as the cost ranges from trivial to structural.
  • Anti-roll Bars — 3.9% of tests. Worn anti-roll bar links or bushes. Inexpensive but often recurring.
  • Springs — 3.7% of tests. A broken or sagging coil spring. Replaced in pairs, so it is not the cheapest failure.
  • Exhaust Emissions — 3.5% of tests. The car exceeded its emissions limits. Can be a sensor or a service, but on a diesel it can also mean an expensive filter or catalyst.
