Used BMW 3 Series cars

Since its launch in the 1970s, the 3 Series has been the brand’s bestselling model. It is one of the most desirable midsized cars on the market. It appeals to many drivers, from those who want a sporty car for day-to-day driving to those in need of decent space for the family. It’s also popular among commuters who need to put in long miles for work.

The BMW 3 Series is a compact executive vehicle and a perfect example of German automotive excellence. Larger than the 1 Series hatchback yet smaller than the 5 Series, the 3 Series has all-rounder appeal. It’s comfortable to drive on long motorway journeys and country lanes. As it's also compact in the executive vehicle class, it's easy to park. The 3 Series comes in a range of body styles. Body styles include the traditional saloon, a coupé, estate and high-performance M3. There’s a great variety of engine options too, including a range of petrol and diesel as well as hybrids.

Competition comes from the Audi A4 and Mercedes-Benz C-Class. The model also stands up well against saloons from luxurious brands like Jaguar. The BMW 3 Series offers a premium driving experience with enhanced handling and performance.

BMW 3 Series updates and facelifts

BMW first released the 3 Series in 1975 in two-door coupé body styles only. It was following the Mk2’s release in 1982 that four-door, convertible and estate versions became available. The Mk2 also brought a diesel engine option alongside its petrol engines. BMW first introduced the M3 with the Mk2 model in 1986. It was called the BMW M3 E30. The M3 E30 was built on the same platform with a high-speed concept four-cylinder petrol engine. The Mk3 3 Series in 1990 brought a hatchback variant. This was the first generation of the 3 Series to offer six-speed manual or five-speed automatic transmission. The Mk3 also had improved suspension.

BMW released the fourth generation 3 Series in 1997. The Mk4 brought with it updated technology available on the model. It included sat-nav, rain-sensing wipers, LED taillights and an electronic brake force display. In 2004, the Mk5 dropped the hatchback variant from its body styles. This generation saw the introduction of a turbocharged petrol engine. The Mk5 M3 received a powerful V8 engine.

The Mk6 saw the greatest change in body styles available on the 3 Series. In 2011, the coupé and convertible were removed from the lineup. The body styles were relaunched after a design update as the BMW 4 Series. The 3 Series added a new body style, a long-wheelbase hatchback called the 3 Series Gran Turismo. The Mk6 also offered a plug-in hybrid engine option. This generation brought many trims and personalisation options, meaning models from this era vary greatly.

BMW’s 3 Series is now in its seventh generation. This version was the first to give the estate an M3 option. It also has a curved touchscreen for everything from music and sat-nav to climate control. This generation continues to offer a mix of petrol, diesel and hybrid powertrains. It received a facelift in 2022 that gave it an updated front and rear, along with a newer iDrive 8 infotainment system.

A wide variety of trims, engine sizes, transmissions and colours are available with a used BMW 3 Series. Examples include the 320d, 320i, 330e, 330d, m340i and the touring body type for those needing a little more room.

Practicality and style of the car

The 3 Series is a practical yet premium vehicle that can effortlessly handle everything from the daily commute to long-distance adventures. It has a length of 4,709mm, a height of 1,442mm and a width of 1,827mm. A stylish and spacious cabin means comfort is guaranteed. There is plenty of space in the front and rear cabin, with ample leg and headroom.

Most of the saloon and coupé models offer 480 litres of boot space. This is the same as the Audi A4 and more than the Mercedes-Benz C-Class. With the rear seats folded, there is 1,510 litres of space for larger items. The seats fold in a 40:20:40 split. This gives you more versatility to take bulky or long items along with passengers in the back. Some variants have technology that lets you open the boot by swiping your foot under the rear bumper. Most current 3-series models are fitted with run flat tyres as standard.

The hybrid model offers 375 litres of boot space which is 105 litres less than the saloon. This is due to electrical equipment for the hybrid battery system taking up more of the floor space. The convertible model offers 350 litres of boot space with the roof up, and 210 litres when it is down. The BMW 3 Series Touring offers the most boot capacity with 500 litres of space.

If you’re planning on adventurous weekends away, the BMW 3 Series is up to the task of towing 1,800kg. That’s the capability needed to tow a caravan or a trailer of sports equipment.

Running costs

The 3 Series sits between insurance groups 18 to 50. The cost of insurance will differ depending on the chosen trim level, transmission-type and engine size. A 330e (from 2019 onwards) typically sits between insurance groups 33 to 36. Insurance costs are similar to rivals. The Audi A4 starts at a lower group of 19 and spans to 44, and the Mercedes-Benz C-Class ranges from groups 23 to 47.

Tax rates are also similar to the competition, starting at £180 a year. Some models attract the additional rate of £390 for their first five years after registration. The average CO2 emissions in grams of carbon dioxide equivalent per kilometre for segment D cars in the UK is 199.2/km for petrol, 162g/km for diesel, and 48g/km for BEVs. CO2 emissions on a 3 Series can range anywhere from 30 g/km to 247 g/km. The cost of taxing a 3 Series will largely depend on engine type and emissions. Additionally, maintenance and repair costs can be kept low providing the vehicle is regularly serviced and well looked after.

How a used BMW 3 Series drives

Most used BMW 3 Series cars for sale have a diesel engine. This is because these powertrains proved most popular with new buyers. These are typically either a 2.0-litre 318d engine that produces 148bhp or the 320d version that produces 181bhp. The more powerful of the two reaches 0-62mph in 5.8 seconds. For an even faster diesel, look out for the M340i six-cylinder unit that produces 335bhp. It can hit 0-62mpg in 4.6 seconds. For the diesel engines, mpg figures range from 54.3 to 62.8.

Petrol options are available but there are fewer around. In terms of output, the 2.0-litre petrol four-cylinder 320i engine produces 182bhp. It can achieve 0-62mph in just over seven seconds. The more powerful 245bhp unit can achieve the same acceleration in 5.9 seconds. The 3 Series petrol units return between 41.5mpg to 44.1mpg.

There are also hybrid powertrains in the mix. The 330e combines a 2.0-litre four-cylinder petrol unit with an electric motor for a total output of 288bhp and 420Nm of torque. Thanks to the added electric boost, it can reach 0-62mph in 5.8 seconds. It’s a plug-in hybrid, meaning it can drive on electric-only mode, with a quoted figure of up to 37 miles. It also returns between 42.2mpg and 62.8mpg. Rear-wheel drive models typically deliver the most miles per gallon.

Most BMW 3 Series models are rear-wheel drive and mated to an eight-speed automatic gearbox. However, you may find some models with a six-speed manual transmission. These versions tend to be paired with the less powerful engines. For more traction in adverse weather conditions and on more challenging roads, look for models marked XDrive. These are all-wheel drive. BMW’s xDrive technology offers an intelligent all-wheel drive (AWD) system. xDrive maximises driving performance on a variety of road surfaces and in a variety of conditions. It is available on the M340d and M340i.

BMW also offer their EfficientDynamics Plus technology. This was designed by BMW as a strategy to minimise fuel consumption and CO2 emissions emitted by their models. The technology minimises fuel consumption and CO2 emissions without impacting handling or performance. For those who prioritise fuel economy and lowering their emissions, a model marked with EfficientDynamics Plus is an excellent option.

Features you can expect in a BMW 3 Series

Interior

The BMW 3 Series set the standard for a compact saloon that offers generous space inside. Newer versions have a longer wheelbase than the Audi A4 and Mercedes-Benz C-Class. Therefore, there is more room for passengers in the back to relax. It is best suited to two adults in the back on long journeys, but the middle seat can fit in an adult too.
