Used Mercedes-Benz B-Class review: 2019-2023
By David Morley · 25 Oct 2026
Mercedes-Benz has never been afraid to pioneer new tech, trends and styling. But you could argue the brand’s more conventional, old-school, take on what a compact family car could be, was the B-Class’ biggest hurdle. Certainly, by the time the world arrived at 2019, and the W247 (in Benz-speak) landed in showrooms, the concept Mercedes was chasing was definitely out of fashion. While other carmakers were adding plastic wheel-arch flares, larger bumpers and a jacked-up ride height to cash in on the tidal wave of compact SUV ownership, Mercedes-Benz stuck with a more traditional people-mover concept. The writing was already on the wall, of course, and you suspect that was the mood even within M-B, as the B-Class range shrunk from a choice of engines and trim levels to a single drivetrain package and a single trim level. And by 2024, it was all over for the concept as far as Mercedes-Benz in Australia was concerned, and the B-Class disappeared from price-lists. But a lack of fashion-sense has never meant a particular car has no other redeeming features, and the Mercedes B180 (as the single model was badged) certainly had its followers. You get the feeling, however, that much of the appeal might have been an adverse reaction in some quarter to the march of the SUV. But that was never enough to sustain the B-Class as a stand-alone, single-spec model (although, like many M-Bs, there were packages the buyers could specify). Mechanically, the B180 used a 1.3-litre turbocharged petrol engine driving through a seven-speed dual-clutch transmission to the front wheels. It was a five-door vehicle with seats for five and sold against vehicles like the Audi A3, BMW 2-Series Active Tourer and Volvo V40. The B180’s biggest problem was that it was simply an old-fashioned concept; a people-mover at a time when everybody wanted an SUV. But it was also flawed in terms of its driveline and the combination of the small turbocharged engine which could feel slow to build boost, and the dual-clutch transmission meant progress was not always as composed or serene as a Mercedes-Benz badge suggested. Quality, however, was better than some less recent Benzes and the multimedia system was modern and sophisticated. The B180 was also a very safe car with a great package of inclusions to keep you safe before and after a crash, including side-curtain airbags for every outboard seating position. As such, it makes decent sense for a younger or first-time driver, as well as smaller families. Modern Mercedes-Benzes don’t seem to share the same reputation for bank-vault reliability as some of the brand’s previous efforts. But to be fair, the B-Class of this era was a decently reliable car. That’s on the condition, of course, that it’s been serviced and maintained correctly and driven appropriately. The major problem areas with the Mercedes B180 are shared with many other cars of this era and this level of technology. Probably the main issue is the dual-clutch transmission which can be jerky on take-off and then shift harshly. Often, this is traced to old or dirty transmission fluid which a full service should solve. In some cases, the problem may be with the electronic control module for the transmission. Oil leaks are not unknown on the W247, so check under the car or on the ground where it normally parks. The fuel injectors are also somewhat prone to carbon build-up which reduces their efficiency and plays against performance and fuel economy. You should also perform a full and complete check of all the car’s electronic functions before making a decision to purchase. Make absolutely sure that every button and switch does what it is supposed to and run through all the functions of the multimedia system. Don’t forget to check the air-con blows cold and that the cruise-control works properly. The B180 was recalled only once, to warn owners that the emergency call function (after a crash) was potentially not working. A software glitch meant the car may have deactivated this function without the owner knowing. The good news was this recall required no action by the owner, as the software update was to be delivered to the car over-the-air from Mercedes-Benz. This vehicle was not subject to a facelift or other revisions during its lifespan, so there are no 'good' or 'bad' production years. In any case, as with any second-hand car, you should buy on condition, kilometres travelled and – above all else – the service history. Since the B180 was largely reserved for urban duties (and the fact that it’s still a relatively young car) only a handful for sale right now have travelled more than 100,000km, and the vast majority a lot less than that. That makes it a bit difficult to forecast what the useful life of a B180 might be, but you need to consider that the small turbocharged engine works pretty hard and that any car like this can fall victim to slack maintenance and servicing. The other point to remember is that racking up big distances in this model will make it potentially a lot more difficult to move on when it’s time to trade up. There was only one model and trim level offered in the B180 of this era, so there are no real choices to be made in terms of which variant to buy. That said, Mercedes-Benz has always been very keen on extras packages and this car was no different. With that in mind, we’d look for an example with the upgrade from synthetic leather to genuine hide, and what’s called the Vision Pack which included the full-length panoramic sunroof. The B180 was a sub-$50,000 car when it was brand-new, which means prices are getting more reasonable now, but still a substantial outlay for what is a small people-mover. The most affordable examples are now popping up for sale in the high-teens and for that you’ll be buying a car with something like 100,000km on its odometer. A fully loaded B180 with super low kilometres (less than 30,000km) on board will be closer to $30,000 with $35,000 being asked for the very best examples with all the option packs. The M-B brand has been around in Australia for a long time now, and even though its dealer network is not as extensive as some, you’d be surprised at some of the regional centres that do, in fact, boast a Mercedes dealership (the cars were always popular with farmers in the good years). But beyond that, there’s also an extensive network of independent specialists who know their way around the brand and the cars. They can also often supply parts at a lower cost than dealerships. There’s also a huge online supply of M-B parts thanks to its status as an established global brand. Mercedes cars are highly regarded in many countries, meaning there are some good bargains to be had by shopping globally on the internet. The B-Class generally and the W247 B-Class specifically, were never great sellers for Mercedes-Benz in Australia. It’s difficult to know how many were sold overall, but estimates put the number at around 3000 examples.
